Both tools support diagramming and collaboration, but OpenCharts ships AI generation, real-time multiplayer, and full export to PNG/SVG/PDF/PPTX on the free plan — plus an MCP server for AI agents — while Lucidchart gates AI features and collaborator counts behind paid tiers. **Choose OpenCharts when:** - You want AI flowchart generation from a PDF or prompt on day one without paying. - Your team needs unlimited real-time collaborators on a free plan. - You also need notes, presentations, and a whiteboard in the same workspace. - You want an MCP server you can wire into Warp, Claude Desktop, Cursor, or VS Code. - You're comparing AI-first diagramming tools rather than enterprise-only solutions. **Choose Lucidchart when:** - You're already on a paid Lucid Suite subscription with deep enterprise SSO/IT integrations. - You need Lucidchart's specific shape libraries (e.g. AWS official iconography, certain ERD specialty packs). - You depend on Lucid's existing Visio import fidelity for legacy stencils. - You're building exclusively for the Microsoft 365 / Google Workspace marketplaces and need Lucid's deep integrations there. **Feature comparison:** - Free plan AI flowchart generation: OpenCharts — Yes — included on every plan | Lucidchart — Limited; AI features mostly paid - Document → flowchart (PDF/PPTX/image): OpenCharts — Yes — drop a file, get an editable flowchart | Lucidchart — Manual import, limited AI extraction - Real-time multiplayer collaborators: OpenCharts — Unlimited on every plan | Lucidchart — Capped per plan; paid tiers required for larger teams - Threaded comments & version history: OpenCharts — Free | Lucidchart — Free with limits; advanced history paid - Whiteboard mode: OpenCharts — Built in (one click flowchart ↔ whiteboard) | Lucidchart — Separate Lucidspark product - Notes & presentations in same workspace: OpenCharts — Yes — Notes editor + AI Presentations | Lucidchart — No (requires separate tools) - Public MCP server for AI agents: OpenCharts — Yes — 19 tools, bearer auth | Lucidchart — No public MCP server - Export PNG / SVG / PDF / PPTX / DOCX / JSON: OpenCharts — All free | Lucidchart — Some formats gated by plan - Browser-only, no install: OpenCharts — Yes | Lucidchart — Yes **Pricing:** OpenCharts is free forever with no credit card. Paid tiers raise AI generation limits and add team-management features but never gate the core diagramming or collaboration. Lucidchart's free plan caps documents and reserves AI plus advanced sharing for paid tiers starting around $7.95/user/month. **Migration:** Export your Lucidchart documents as PDF, PNG, or .vsdx, then drag the file into OpenCharts. Theo extracts the structure and rebuilds it as native, editable nodes and edges — no manual rebuild required. **FAQ:** Q: Is OpenCharts a free alternative to Lucidchart? A: Yes. OpenCharts has a free plan with no credit card required that includes AI flowchart generation, unlimited real-time collaborators, comments, version history, and full export. Lucidchart's free plan caps documents at three and gates AI behind paid tiers. Q: Can I import my Lucidchart documents into OpenCharts? A: Yes. Export from Lucidchart as PDF, PNG, or VSDX, then drop the file into OpenCharts and Theo extracts the diagram structure into native editable nodes and edges that you can edit, theme, and re-export. Q: Does OpenCharts support BPMN, swimlane, and ER diagrams like Lucidchart? A: Yes. OpenCharts supports 20+ node types including swimlane, BPMN-style processes, ERD entities, decision diamonds, and group containers. Templates are available for each diagram family. Q: How is real-time collaboration different? A: OpenCharts ships free real-time multiplayer with unlimited collaborators, live cursors, node locking, threaded comments, and one-click share links with viewer/commenter/editor permissions on every plan. Lucidchart requires paid tiers for larger team sizes and gates many sharing controls. Q: Can OpenCharts export to PowerPoint and PDF? A: Yes. Every flowchart can be exported to PNG, SVG, PDF, PPTX, DOCX, XLSX, or JSON. You can also generate a public share link or embed the diagram on any website. Q: Does OpenCharts have a Visio replacement story? A: If you're moving off Lucidchart's Visio import workflow, you can drop a .vsdx export through OpenCharts and Theo will reconstruct the structure. For complex stencil libraries you may need to recreate a few node styles, but everyday process diagrams transfer cleanly. Q: Is there an OpenCharts API or AI-tool integration? A: Yes. OpenCharts exposes a public MCP (Model Context Protocol) server with 19 tools that lets external AI tools — Warp, Claude Desktop, Cursor, VS Code, Windsurf — read and write OpenCharts artifacts directly with bearer-token auth. ### OpenCharts vs Miro URL: https://opencharts.com/compare/miro Title: OpenCharts vs Miro — Whiteboard, Flowcharts, AI in One OpenCharts is a free, AI-native alternative to Miro that combines an infinite whiteboard with structured AI flowcharts, rich notes, and AI-built presentations in a single workspace. Both tools excel at real-time visual collaboration, but OpenCharts adds one-click whiteboard-to-flowchart conversion, document-to-diagram AI extraction, and an MCP server for AI agents — all on the free plan with unlimited collaborators. **Choose OpenCharts when:** - You want AI to turn a PDF, prompt, or whiteboard sketch into a structured flowchart automatically. - You need both freehand whiteboard and structured flowcharts/notes/slides in one tool. - Your team is cost-sensitive and you want unlimited free collaborators. - You want to drive the canvas from AI agents (Warp, Claude Desktop, Cursor) via MCP. - You'd like notes and slide decks without context-switching between separate apps. **Choose Miro when:** - You depend on Miro's huge ecosystem of marketplace apps and integrations. - Your team is already standardized on Miro and your facilitation playbooks live there. - You need Miro's specific facilitation features like timer-driven workshops and voting at the scale of a 200-person workshop. - You require Miro's enterprise SSO/IT controls already approved by your security org. **Feature comparison:** - Infinite whiteboard: OpenCharts — Yes — built in | Miro — Yes (core product) - AI flowchart from a PDF/PPTX/image: OpenCharts — Yes — drag and drop | Miro — Limited; sticky-note AI assist only - Whiteboard → structured flowchart: OpenCharts — One-click conversion | Miro — Manual rebuild - Rich notes editor in same workspace: OpenCharts — Yes (block editor with inline AI) | Miro — No (sticky notes only) - AI presentations in same workspace: OpenCharts — Yes (deck builder + brand themes) | Miro — No (separate tools) - Free real-time collaborators: OpenCharts — Unlimited | Miro — Capped per plan - Threaded comments + version history: OpenCharts — Free on every plan | Miro — Capped on free; full history on paid - Public MCP server: OpenCharts — Yes (19 tools) | Miro — No - Export PPTX/PDF/PNG/SVG/DOCX/JSON: OpenCharts — All free | Miro — Some paid **Pricing:** OpenCharts is free forever; paid tiers raise AI credit limits and add team management. Miro's free plan caps editable boards at 3 and limits collaborators per board; paid tiers start around $8/user/month and gate advanced apps and admin controls. **Migration:** Export your Miro board as a PDF or image, drop it into OpenCharts, and Theo rebuilds the structure as native nodes and edges. For sticky-note brainstorms, paste the text into a Notes project — Theo will organize it into a structured outline or flowchart on demand. **FAQ:** Q: Is OpenCharts a free Miro alternative? A: Yes. OpenCharts ships an infinite whiteboard, structured flowcharts, notes, and AI presentations on a free plan with unlimited real-time collaborators and no credit card required. Miro's free plan limits editable boards and collaborators. Q: Can I import my Miro boards? A: Yes. Export your Miro board as PDF or PNG, drop the file into OpenCharts, and Theo extracts the structure into editable nodes and edges. For text-heavy brainstorms, you can paste the content directly into a Notes project and ask Theo to convert it into a flowchart or whiteboard. Q: Does OpenCharts have facilitation features like timers and voting? A: OpenCharts focuses on AI-native creation: flowcharts, whiteboards, notes, and presentations. It supports threaded comments, presence, and shared cursors but does not yet include Miro's full facilitation suite (timers, voting widgets, breakout rooms). Q: Can multiple people draw on the same whiteboard at once? A: Yes. The whiteboard supports real-time multiplayer editing with live cursors, presence indicators, and node locking. Multiple users can draw, add shapes, embed images, and annotate the same board simultaneously. Q: How does the AI flowchart generator compare to Miro AI? A: OpenCharts AI extracts complete editable flowcharts from PDFs, PowerPoint, images, or text prompts in 5–15 seconds, including swimlanes, decision branches, and BPMN-style processes. Miro AI primarily helps generate sticky-note clusters and summarize boards rather than producing structured diagrams. Q: Can I drive OpenCharts from Claude Desktop or Cursor? A: Yes. The public OpenCharts MCP server exposes 19 tools (project CRUD, AI extraction, Theo chat, research) that any MCP-compatible client like Warp, Claude Desktop, Cursor, VS Code, or Windsurf can call with a bearer token. ### OpenCharts vs Whimsical URL: https://opencharts.com/compare/whimsical Title: OpenCharts vs Whimsical — Free AI Flowcharts & More OpenCharts is a free, AI-native alternative to Whimsical that covers flowcharts, mind maps, sticky-note boards, wireframes, notes, and presentations in a single workspace. Both tools focus on fast, opinionated visual thinking, but OpenCharts adds AI flowchart generation from documents, real-time multiplayer with unlimited collaborators on the free plan, and a public MCP server external AI agents can drive. **Choose OpenCharts when:** - You want AI to generate diagrams from a PDF or text prompt rather than building each one by hand. - Your team is cost-sensitive and needs unlimited free collaborators. - You also want notes and AI-built slide decks alongside diagrams. - You'd like to wire the canvas into AI agents through MCP. - You're choosing between minimalist visual tools but need AI-native generation. **Choose Whimsical when:** - You only need Whimsical's specific opinionated flowchart and wireframe styles and value its low feature surface area. - Your team is already using Whimsical Boards heavily. - You don't need notes, slide decks, or AI generation — just quick handcrafted diagrams. **Feature comparison:** - AI flowchart generation from PDF / prompt: OpenCharts — Yes — included free | Whimsical — Whimsical AI assist only on text generation - Mind maps: OpenCharts — Yes (whiteboard or flowchart node types) | Whimsical — Yes - Wireframes: OpenCharts — Code Canvas + image canvas | Whimsical — Yes (built-in) - Notes editor with inline AI: OpenCharts — Yes | Whimsical — Whimsical Docs (separate) - AI presentations: OpenCharts — Yes (deck builder) | Whimsical — No - Free real-time collaborators: OpenCharts — Unlimited | Whimsical — Capped on free plan - Public MCP server for AI agents: OpenCharts — Yes | Whimsical — No - Whiteboard ↔ flowchart conversion: OpenCharts — One click | Whimsical — Manual - Export PPTX / DOCX / PDF / SVG / JSON: OpenCharts — All free | Whimsical — Limited **Pricing:** OpenCharts is free forever; paid tiers raise AI credit limits. Whimsical's free plan caps you at four editable items and gates AI features and collaboration in the paid Pro tier. **Migration:** Export Whimsical documents as PNG or PDF, drop them into OpenCharts, and Theo rebuilds them as native flowchart nodes. Whimsical Docs export to plain Markdown or PDF, which OpenCharts Notes can import directly via paste or upload. **FAQ:** Q: Is OpenCharts free like Whimsical's free plan? A: Yes — and the OpenCharts free plan is more generous: unlimited editable projects, unlimited real-time collaborators, AI flowchart generation, and full export. Whimsical's free plan caps you at four editable items. Q: Can I do mind maps in OpenCharts? A: Yes. Mind maps are supported via the radial-layout option in the flowchart auto-layout engine, or you can build them freehand on the whiteboard. There are templates for both styles. Q: Does OpenCharts have wireframes? A: OpenCharts ships a Code Canvas for live in-browser app prototypes plus an Image Canvas for AI image briefs and mockups. For pure UI wireframing, the whiteboard's shape library covers most basic wireframe needs. Q: Can AI generate a flowchart for me? A: Yes. Drop a PDF, PowerPoint, or image into OpenCharts and Theo generates an editable flowchart in 5–15 seconds. Or describe the process in plain English and Theo builds the diagram from your prompt. Q: How big can a project get? A: OpenCharts has no four-item cap like Whimsical's free tier. You can create unlimited projects across flowcharts, whiteboards, notes, and presentations on the free plan. Q: Does OpenCharts have an API? A: Yes. The public MCP server exposes 19 tools so external AI clients (Warp, Claude Desktop, Cursor, VS Code) can read and write OpenCharts artifacts. Bearer-token auth, 120 req/min rate limit. ### OpenCharts vs Mural URL: https://opencharts.com/compare/mural Title: OpenCharts vs Mural — Free AI-Powered Visual Workspace OpenCharts is a free, AI-native alternative to Mural that pairs an infinite whiteboard with structured AI flowcharts, rich notes, and AI-built presentations in one workspace. Mural focuses on facilitator-led workshops; OpenCharts focuses on AI-native creation across artifact types — including a one-click whiteboard-to-flowchart conversion and a public MCP server external AI agents can call directly. **Choose OpenCharts when:** - You want AI to extract or generate structured diagrams alongside freeform whiteboarding. - You need notes and slide decks in the same tool. - Your team wants unlimited free collaborators. - You're integrating an AI agent (Claude Desktop, Cursor, Warp) with your visual workspace. **Choose Mural when:** - Your team's facilitation rituals are anchored in Mural's specific templates and methodology. - You need Mural's deeper enterprise governance, workshop modes, and Microsoft-specific integrations. - Your customer success org runs Mural-trained workshops at scale. **Feature comparison:** - Infinite whiteboard: OpenCharts — Yes | Mural — Yes (core product) - AI flowchart from documents: OpenCharts — Yes — drag in a PDF | Mural — Limited; mostly sticky-note AI - Structured flowcharts (20+ node types): OpenCharts — Yes | Mural — Manual; basic shapes - Notes + presentations in same workspace: OpenCharts — Yes | Mural — No - Free unlimited collaborators: OpenCharts — Yes | Mural — Capped on free plan - Public MCP server: OpenCharts — Yes (19 tools) | Mural — No - Export PPTX / PDF / DOCX / SVG / JSON: OpenCharts — All free | Mural — Some paid **Pricing:** OpenCharts is free forever; paid tiers raise AI credit limits. Mural's free Starter plan caps murals to 3 and gates voting, timers, and workshop facilitator features behind paid tiers starting around $9.99/user/month. **Migration:** Export your Mural canvas as PDF or PNG, drop it into OpenCharts, and Theo rebuilds the structure. Sticky-note clusters can be pasted into a Notes project where Theo can convert them into a structured flowchart or outline. **FAQ:** Q: Is OpenCharts a free alternative to Mural? A: Yes. OpenCharts has a generous free plan with unlimited editable projects and real-time collaborators, plus AI flowchart generation, notes, and presentations. Mural's free plan caps murals at three. Q: Does OpenCharts replace Mural for facilitated workshops? A: It depends on your workshop format. OpenCharts covers brainstorming, mind maps, retros, and journey maps with templates and real-time collaboration. Mural's specific facilitator features (timers, voting widgets, structured workshop flows) are not all present in OpenCharts today. Q: Can I import my Mural canvases? A: Yes. Export your Mural as PDF or PNG and drop it into OpenCharts. Theo rebuilds the structure into editable diagram or whiteboard elements. Q: How does AI compare? A: OpenCharts AI generates complete editable flowcharts from PDFs, PPTX, images, or text prompts in seconds. Mural's AI mostly summarizes sticky-note clusters and suggests groupings. Q: Can I run real-time collaboration with my whole team? A: Yes. The free OpenCharts plan supports unlimited real-time collaborators across all canvas types with live cursors, presence avatars, threaded comments, and node locking. ### OpenCharts vs FigJam URL: https://opencharts.com/compare/figjam Title: OpenCharts vs FigJam — Free AI Flowcharts + Whiteboard OpenCharts is a free, AI-native alternative to FigJam that pairs an infinite whiteboard with structured AI flowcharts, rich notes, and AI-built presentations.

Theo identifies the central idea, primary branches, sub-branches, and supporting facts, then applies a radial or top-down layout. Mind maps live alongside flowcharts, whiteboards, and notes in the same workspace, with real-time multiplayer collaboration and exports to PNG/SVG/PDF/PPTX. **How it works:** 1. **Describe your topic** — Type a central idea (‘launch plan for X’, ‘research for thesis on Y’) or paste a long note. Theo extracts the structure. 2. **Theo proposes a radial map** — Theo identifies primary branches and sub-branches, lays them out radially or top-down, and color-codes by branch. 3. **Edit, expand, and theme** — Drag branches, add sub-nodes, attach images and data tables, switch between radial and top-down layouts, and pick a theme. 4. **Share or export** — Public share link or export to PNG, SVG, PDF, PPTX, DOCX. Convert the mind map to a flowchart in one click for a structured workflow. **Features:** - Radial, top-down, and force-directed layouts - Image and emoji attachments per node - Mind map ↔ flowchart conversion - Real-time multiplayer collaboration with cursors and threaded comments - Templates: brainstorm, project plan, research outline, study map **FAQ:** Q: Can I generate a mind map from a long note? A: Yes. Open the Notes project, ask Theo to ‘turn this into a mind map’, and Theo extracts the headings, key terms, and supporting facts into a radial map. You can keep iterating with follow-up prompts. Q: Is the mind map editable? A: Yes. The output is a fully editable canvas with all OpenCharts tools (themes, comments, multiplayer, export). Q: Can I convert a mind map to a flowchart? A: Yes. One-click conversion turns a radial mind map into a top-to-bottom flowchart, preserving branches as decision paths or sequential steps depending on context. Q: How big can a mind map get? A: Maps with 200+ nodes work well. For larger maps, use group containers to collapse sub-trees and keep navigation snappy. Q: Is this free? A: Yes. Mind map generation, themes, real-time collaboration, and export are included on every plan including the free tier. ### Swimlane diagrams with AI URL: https://opencharts.com/use-cases/swimlane-diagrams Title: AI Swimlane Diagrams — OpenCharts OpenCharts is an AI swimlane-diagram builder that turns a cross-functional process description into an editable swimlane (cross-functional flowchart) in seconds.

Free real-time collaboration, attached data tables for SLAs and KPIs, exports to PNG/SVG/PDF/PPTX, and a public MCP server for AI agents that need to maintain the diagram programmatically. **How it works:** 1. **Describe the cross-functional process** — Tell Theo who is involved (Sales, Onboarding, Billing, Customer) and what each does. Or upload an existing process PDF. 2. **Theo creates lanes and steps** — Theo creates a lane per role, assigns activities to the right lane, draws handoffs, and decision branches. 3. **Refine ownership and SLAs** — Drag steps between lanes, attach data tables for SLAs and KPIs, color-code by status, and add comments. 4. **Share or export** — Public share link or export to PNG, SVG, PDF, PPTX, DOCX, XLSX, JSON. **Features:** - Horizontal or vertical swimlanes - Decision diamonds, parallel paths, loops, and group containers - Attach data tables to any step (SLA, owner, KPI) - Real-time multiplayer collaboration with live cursors and comments - Templates: customer onboarding, support escalation, change management **FAQ:** Q: Can OpenCharts auto-assign steps to lanes? A: Yes. When you describe the process to Theo (or upload a PDF), Theo identifies the actor for each step and places it in the correct lane. You can manually drag steps between lanes anytime. Q: Are vertical swimlanes supported? A: Yes. Switch between horizontal and vertical orientations via the layout toolbar. Q: Can I attach KPIs to each step? A: Yes. Every node supports an attached data table — perfect for SLAs, owners, KPIs, and process documentation. Q: Can swimlane diagrams export to PowerPoint? A: Yes. Export as fully editable PPTX, plus PDF, PNG, SVG, DOCX, XLSX, and JSON. Q: Is this BPMN-compliant? A: OpenCharts supports BPMN-style swimlanes (pools and lanes), gateways, and activities. For strict BPMN 2.0 XML interchange we recommend exporting as image and re-importing into a BPMN-specific tool. ### Decision trees with AI URL: https://opencharts.com/use-cases/decision-trees Title: AI Decision Tree Maker — OpenCharts OpenCharts is an AI decision-tree maker that turns a question, troubleshooting flow, or policy document into an editable yes/no decision tree in seconds. Theo identifies decision points, conditions, and outcomes; lays them out cleanly; and lets you collaborate in real time. Decision trees live in the same workspace as flowcharts, notes, and presentations, with exports to PNG/SVG/PDF/PPTX and a public MCP server for AI agents. **How it works:** 1. **Describe the decision** — Tell Theo the central question (‘Should we approve this loan?’, ‘Which support tier handles this ticket?’) or upload a policy PDF. 2. **Theo proposes the tree** — Theo identifies the decision points, branch conditions, and terminal outcomes, and lays them out as a top-down or radial tree. 3. **Refine branches and labels** — Add or remove branches, edit conditions, attach data tables for risk scores and ownership, and apply themes. 4. **Share or export** — Public share link, export to PNG, SVG, PDF, PPTX, DOCX, JSON, or embed the tree in your help docs. **Features:** - Yes/No, multi-way, and weighted decision branches - Branch labels and risk scores via attached data tables - Top-down, radial, and force-directed layouts - Real-time multiplayer collaboration with comments per node - Templates: troubleshooting, eligibility, approval, support routing **FAQ:** Q: Can the tree have more than two branches per decision? A: Yes. Decision nodes can have any number of outgoing branches with custom labels. Use the same node for multi-way classification or mutually exclusive choices. Q: Can I attach risk scores or weights? A: Yes. Every node supports an attached data table where you can capture risk scores, probabilities, owners, and ownership notes. Q: Can I publish a decision tree as an interactive page? A: Yes. Use a public share link with viewer permission. Recipients can pan/zoom and click into nodes to see attached data. For a guided experience, embed the tree alongside notes that link out to specific branches. Q: Can decision trees be programmatically maintained? A: Yes. The MCP server exposes node-level CRUD so an AI agent or workflow can keep a decision tree in sync with policy changes. Q: Is this free? A: Yes. Decision tree generation, themes, real-time collaboration, and export are included on every plan including the free tier. ### BPMN diagrams with AI URL: https://opencharts.com/use-cases/bpmn-diagrams Title: AI BPMN Diagrams — OpenCharts OpenCharts is an AI BPMN-diagram builder that turns a process description, SOP, or PDF into a BPMN-style diagram (pools, lanes, gateways, activities) in seconds. Theo identifies the actors and decisions, applies a clean horizontal layout, and supports parallel paths, exclusive gateways, and message flows. Free real-time collaboration, attached data tables for SLAs and KPIs, and exports to PNG/SVG/PDF/PPTX/DOCX. **How it works:** 1. **Describe the process** — Tell Theo the process owner, the actors, and the major activities. Or upload an SOP PDF. 2. **Theo builds the BPMN structure** — Pools, lanes, start events, activities, gateways (exclusive, parallel, inclusive), and end events are placed automatically. 3. **Refine handoffs and SLAs** — Move activities between lanes, attach KPIs, color-code by status, and add comments for review. 4. **Share or export** — Public share link or export to PNG, SVG, PDF, PPTX, DOCX, XLSX, JSON. **Features:** - Pools and lanes for actors and roles - Exclusive (XOR), parallel (AND), and inclusive (OR) gateways - Start/end events and message flows - Attached data tables per activity for SLAs, owners, and metrics - Real-time multiplayer collaboration - Templates: order-to-cash, hire-to-retire, approve-to-pay, incident response **FAQ:** Q: Is this BPMN 2.0 compliant? A: OpenCharts supports the visual semantics of BPMN 2.0 (pools, lanes, gateways, activities, events, message flows). For strict BPMN 2.0 XML interchange we recommend exporting as image and re-importing into a BPMN-specific tool. Roundtrip BPMN XML is on the roadmap. Q: Can I model parallel and exclusive flows? A: Yes. Theo recognizes ‘meanwhile’, ‘in parallel’, and ‘either/or’ language to build parallel and exclusive gateways. You can also drag gateway nodes manually. Q: Are events supported? A: Yes. Start, end, and intermediate events are supported, including timer and message events. Q: How does this differ from a swimlane diagram? A: Swimlane diagrams are simpler (lanes for roles + activities + decisions). BPMN adds gateways, events, and message flows for richer formal modeling. OpenCharts supports both, and you can convert between them. Q: Is this free? A: Yes. BPMN diagram generation, themes, real-time collaboration, and export are included on every plan including the free tier. ### User flow diagrams with AI URL: https://opencharts.com/use-cases/user-flow Title: AI User Flow Diagrams — OpenCharts OpenCharts is an AI user-flow builder that turns a product description or journey map into an editable user-flow diagram in seconds. Theo identifies screens, actions, decision branches, and edge cases, and lays them out top-to-bottom or left-to-right. Mix screens with whiteboard sketches and notes, collaborate in real time, and export to PNG/SVG/PDF/PPTX for design reviews and product specs. **How it works:** 1. **Describe the flow** — Tell Theo the product, the persona, and the goal (‘new user signing up for trial, sees pricing, abandons, comes back via email’). 2. **Theo builds the flow** — Theo creates a screen-by-screen flow with action nodes, decision branches (yes/no), and edge cases (errors, cancellations). 3. **Add screen mocks** — Drag screen images onto nodes, attach data tables for analytics events, and group by lifecycle phase. 4. **Share or export** — Public share link or export to PNG, SVG, PDF, PPTX, DOCX, JSON. **Features:** - Screen, action, decision, error, and end-state node types - Whiteboard mode for freehand wireframes alongside structured flows - Templates: signup, checkout, onboarding, subscription cancellation - Real-time multiplayer collaboration with cursors and comments - Image embeds for screen mockups **FAQ:** Q: Can I attach analytics events to each step? A: Yes. Every node supports an attached data table where you can record event names, properties, owner, and notes. Q: Can I import Figma frames? A: Direct Figma integration is on the roadmap.

The Templates gallery includes signup, checkout, onboarding, subscription cancellation, and SaaS first-run experience flows. All editable and AI-customizable. ## Glossary — diagramming and process-mapping definitions 196 entries. Each starts with a one-sentence definition (citation magnet) and a longer explanation. ### Theo AI URL: https://opencharts.com/glossary/theo-ai Definition: Theo AI is the OpenCharts assistant — a multi-mode, multi-modal agent that creates flowcharts, whiteboards, notes, presentations, code, podcasts, movies, and more from a single chat. Theo is the conversational fabric that ties the entire OpenCharts platform together. A single chat can route to any of 11+ specialized modes, call dozens of creation tools, query your memory, run skills, dispatch hooks, execute workflows, and stream artifacts — all without leaving the conversation. Architecturally, Theo is a Tier 1/2/3 orchestrator: simple requests stay in fast single-shot mode, intent-classified specialist requests hand off to a tuned model, and complex requests fan out to a planner-specialist-evaluator multi-agent DAG. Tools, prompts, models, and credit accounting all flow through the unified Theo catalog. Theo lives in the dashboard sidebar mascot, the full chat surface at /chat, the Telegram bot, the macOS Theo Desk app, the MCP server, and embedded surfaces like Notes inline AI and the Whiteboard panel. **Examples:** “Make me a flowchart of our hiring process” → flowchart project; “Plan a content calendar for our product launch” → social mode + calendar artifact; “Research the EU AI Act and brief me” → deep research + research document; “Generate a podcast from these notes” → audio episode in the Podcast Hub **Also known as:** Theo, Theo Assistant, OpenCharts AI ### Theo Mascot URL: https://opencharts.com/glossary/theo-mascot Definition: The Theo Mascot is the animated sidebar companion that gives Theo a face — it reacts to your activity, surfaces tips, and provides a one-click entry point into chat, voice, and stealth mode. The mascot lives in the bottom of the OpenCharts dashboard sidebar. It animates between idle, talking, listening, and celebratory states based on what you’re doing in the workspace, and offers a single click into the Theo chat surface or voice mode. On first run, the mascot also handles the welcome sequence and Theo Movie intro, and exposes shortcut chips to trigger common actions (new flowchart, summarize, voice mode, stealth). **Examples:** Idle bounce in the sidebar; Speech bubble with a hint when a project is empty **Also known as:** sidebar mascot, Theo companion ### Generative UI URL: https://opencharts.com/glossary/generative-ui Definition: Generative UI is OpenCharts’ pattern of streaming live, interactive components — flowcharts, tables, code previews, calendars, image canvases — directly into the chat as Theo answers. Where most chat tools render plain text, OpenCharts streams typed artifacts: a flowchart that opens in the editor, a table you can sort inline, a code sandbox with a live preview, a calendar you can edit. The artifacts coexist with the chat thread so the conversation and the deliverable are part of the same surface. Generative UI is powered by Theo tool calls (e.g. create_flowchart, create_table, start_calendar_code) and renderers in the chat client. Each artifact card has its own follow-up actions — open, share, iterate, restyle. **Examples:** Streaming flowchart card; Inline editable table; Live code preview **Also known as:** streaming UI, interactive artifacts, tool UI ### Theo Memory URL: https://opencharts.com/glossary/theo-memory Definition: Theo Memory is the personal knowledge graph that remembers your facts, preferences, and instructions across conversations — so Theo gets more useful the more you use it. Memory is split into multiple types — facts (people, projects, products), preferences (tone, format, style), instructions (always include X), and entities derived from the things you build. Memories are extracted automatically by Theo and can also be saved explicitly. Retrieval is tiered: fast keyword retrieval for exact matches, plus a semantic vector index for fuzzy recall. The MCIR pipeline (Memory-Completion Intent Resolution) blends memory hits into intent classification so Theo can resolve “update the deck” to the right project. You can review, edit, and delete every memory from settings. Memory is private to your account and never leaves your tenant. **Examples:** “My brand color is #FF5C00” persisted across decks; “Always write in Spanish unless I ask otherwise”; “Project Aeternum = the SaaS rewrite I’m running” **Also known as:** Theo memories, personal memory ### MCIR (Memory-Completion Intent Resolution) URL: https://opencharts.com/glossary/mcir Definition: MCIR is the intent-resolution pipeline that combines fast regex routing, a small reasoning model, behavioral patterns, and memory context to decide which Theo mode and tools should handle each message. MCIR (Memory-Completion Intent Resolution) is OpenCharts’ replacement for naïve mode toggles. For every incoming user message, the pipeline runs cheap heuristics first, then asks a fast model to score a multi-dimensional intent (action, output format, domain, complexity, framing) using your memory and recent project structure as context. Output is a confidence-scored decision: route directly, ask a clarifying question, or pass through to the previous mode. Resolved intents are recorded so the system learns each user’s personal frequency distributions. **Examples:** Routes “build me a moodboard” to image canvas without a mode switch; Resolves “update it” to the last project you touched **Also known as:** intent V2, MCIR pipeline ### Intent Classifier URL: https://opencharts.com/glossary/intent-classifier Definition: The Intent Classifier is the layer that decides which Theo mode a message belongs to — fast, think, code, image, video, social, learn, research, or others — using regex patterns plus a small AI scorer. The classifier owns the mapping between a free-form message and a structured Theo Intent. It runs first for cheap obvious cases (exact verbs, slash commands), then escalates to a reasoning model to score multi-dimensional intent if no clean match is found. When MCIR is enabled, the classifier feeds a richer pipeline that also blends user memory, behavioral patterns, and recent artifacts before committing to a mode. **Examples:** “draw a flowchart” → flowchart creation; “summarize this PDF” → notes mode + extract **Also known as:** mode router, intent router ### Tool Call URL: https://opencharts.com/glossary/tool-call Definition: A tool call is a structured action Theo invokes during a response — like create_flowchart, send_email, or db_run_sql — that produces a real artifact or side effect, not just text. Tool calls are how Theo turns natural language into actual work. Each tool has a typed schema, a permission descriptor, and a server-side execution path. The model proposes the call, the runtime validates it, and the result streams back to the chat as an artifact card or status update. OpenCharts ships dozens of tools — flowchart, whiteboard, notes, presentation, table, code project, podcast, calendar, image, video, knowledge map, integrations, and more. Skills extend the set with namespaced custom tools. **Examples:** create_flowchart; send_telegram; db_run_sql; create_podcast **Also known as:** function call, tool invocation ### Artifact URL: https://opencharts.com/glossary/artifact Definition: An artifact is any concrete deliverable Theo produces — a flowchart, deck, document, table, podcast, movie, code project, calendar, image, or video — surfaced as an interactive card in chat. Every tool call resolves to a typed artifact: project artifacts (flowchart, whiteboard, notes, presentation, code), media artifacts (image, video, podcast, movie), structured artifacts (table, knowledge map, code plan), and platform artifacts (calendar, learn session, flashcard, quiz). Artifacts live as first-class records in the workspace, can be shared via public links, and follow the same permission model as user-created files. **Examples:** A flowchart card you can open in the editor; A movie card with a Watch Now button **Also known as:** deliverable, output card ### Stop Predicate URL: https://opencharts.com/glossary/stop-predicate Definition: A stop predicate is the rule that decides when Theo should end a multi-step generation — e.g. stop after the calendar tool runs, or after N tool calls in research mode. Stop predicates are how OpenCharts keeps long-running modes scoped without truncating useful work. Each mode declares its own predicate: smart (default), video (stop after a video tool), calendar (stop after Phase A then resume on follow-up). They’re defined once in src/lib/ai/stopPredicates.ts and shared across web chat, Telegram, and the Theo Desk loop so behavior stays consistent everywhere Theo runs. **Examples:** Stop after start_calendar_code in social mode; Stop after the first video tool in video mode **Also known as:** stopWhen, termination rule ### Theo Personality URL: https://opencharts.com/glossary/personality Definition: Theo Personality is your per-account configuration — tone, persona, language, formatting preferences — that gets injected into every system prompt so Theo always sounds like the assistant you want. Personality blends with Theo Memory but lives in user prefs and is bounded — name, pronouns, default language, default tone (concise / friendly / formal / playful), preferred output formats, and any always-on instructions. It’s rendered into the system prompt for every entry point — web chat, Telegram, Theo Desk — so behavior stays consistent across surfaces. **Examples:** “Always answer in Spanish unless asked otherwise”; “Default to concise outlines, then expand on request” **Also known as:** Theo personality config, user persona ### AI Credits URL: https://opencharts.com/glossary/ai-credits Definition: AI Credits are the unit OpenCharts uses to meter Theo usage — every chat reply, image, video, or autonomous skill run consumes a credit amount based on the engine and tools involved. Each plan ships with a base monthly allotment of credits that resets on the billing date. You can top up with one-time credit packs (250K, 500K, 1M). Credits are consumed by the active engine: light chat is cheap, image and video generation are heavier, autonomous skills and workflows draw from a separate daily cap. The catalog-driven credit-multiplier table is the single source of truth and ensures every new engine plugs into accounting automatically. **Examples:** Free plan = 50K credits/month; 1M Credits credit pack add-on **Also known as:** credits, Theo credits ### Credit Pack URL: https://opencharts.com/glossary/credit-pack Definition: A credit pack is a one-time purchase that adds extra AI credits to your account — 250K, 500K, or 1M — that stack on top of your monthly plan allotment. Credit packs are useful when a project pushes you past the monthly base — heavy image/video generation, large skill runs, deep research bursts. Pack credits never expire as long as your account is active and stack on top of monthly allotments. **Examples:** +1M credits before a launch; +500K to run multi-day research skills **Also known as:** AI credits add-on, top-up ### Autonomous Daily Cap URL: https://opencharts.com/glossary/autonomous-daily-cap Definition: The autonomous daily cap is a separate per-day credit budget for background actions — heartbeats, hooks, and workflows — so they can never drain your interactive credit balance. By default, autonomous actions get 10% of your monthly base allotment as a daily cap. When the cap is hit, scheduled skills and workflows pause for the day instead of falling back on your interactive credits, and you get a notification. Combined with per-skill credit guards and consecutive-skip auto-pause, the cap is what makes proactive Theo safe to leave running. **Examples:** Daily cap = 5K credits on the Free plan; Cap reset every 24h **Also known as:** daily cap, background credit budget ### Tier 1/2/3 Orchestration URL: https://opencharts.com/glossary/tier-orchestration Definition: Tier 1/2/3 orchestration is Theo’s adaptive routing — Tier 1 handles single-shot replies, Tier 2 hands off to a tuned specialist, Tier 3 fans out to a planner-specialist-evaluator multi-agent DAG. Tier 1 is the fast path: a direct generateText call against the active mode’s primary engine. Tier 2 dispatches to a specialist agent (e.g. coder, researcher, designer) using a curated tool set and a focused prompt. Tier 3 launches a planner that decomposes the task into sub-agents executed in parallel, then an evaluator that synthesizes the final answer. Routing is decided by the planner gate, which uses message complexity, requested artifacts, and intent confidence to pick the cheapest tier that will produce a satisfying answer. **Examples:** “What time is it in Tokyo?” = Tier 1; “Build a launch plan” = Tier 3 **Also known as:** multi-agent orchestration, Theo orchestrator ### Fast Mode URL: https://opencharts.com/glossary/fast-mode Definition: Fast Mode is Theo’s default conversational engine — instant replies, low credit cost, and the right pick for quick questions, drafts, and lightweight artifact creation. Fast Mode keeps the conversation moving with minimal latency. It’s tuned for everyday writing, brainstorming, summarization, and one-off artifact creation. When a request needs deeper reasoning, Theo escalates to Think or Research automatically. **Examples:** “Draft a follow-up email”; “Make a 5-bullet outline” **Also known as:** default mode, quick chat ### Think Mode URL: https://opencharts.com/glossary/think-mode Definition: Think Mode runs Theo’s deep reasoning engine — slower but with better answers for hard problems, multi-step plans, and code or analysis tasks where correctness matters. Think Mode trades latency for quality. It uses a reasoning-first engine (Theo Reason) with extended deliberation budgets, and is the right choice when an answer must be checked, an argument must be tight, or code must compile on the first try. **Examples:** “Reason about this contract clause”; “Plan a migration with rollback steps” **Also known as:** reasoning mode, deep think ### Explore Mode URL: https://opencharts.com/glossary/explore-mode Definition: Explore Mode pairs conversational Theo with proactive web search and inline citations — perfect for “tell me about X” questions, fact-finding, and quick discovery. Explore is Theo’s curious mode. Every reply pulls live sources from the web, weaves citations into the answer, and offers follow-up questions and a one-click knowledge map of the topic. It’s lighter than Research (no multi-pass synthesis) and faster than Think (no extended reasoning), so it’s the right default for everyday discovery. **Examples:** “Tell me about the EU AI Act”; “Compare React Server Components vs. Astro Islands” **Also known as:** discovery mode, web search mode ### Research Mode (Deep Research) URL: https://opencharts.com/glossary/research-mode Definition: Research Mode runs a multi-pass background pipeline — searches dozens of sources, synthesizes findings, and produces a polished, downloadable research document. Research Mode is built for serious work: market briefs, due diligence, literature reviews, white papers. Theo plans the investigation, fans out web searches, evaluates sources, and writes a structured document with cited sections. Long-form research runs as a background pipeline so it doesn’t block the chat — you get a deep-link to the live progress and a final downloadable PDF/DOCX research artifact. **Examples:** “Brief me on competitive AI diagram tools”; “Build a market scan for synthetic biology in 2026” **Also known as:** deep research, research agent ### Code Mode URL: https://opencharts.com/glossary/code-mode Definition: Code Mode generates live, multi-file code artifacts with an in-browser preview — share, fork, and iterate on React, Vue, vanilla JS, Python, or full-stack apps without leaving chat. Code Mode pairs Theo with the Code Canvas — an in-browser runtime that renders projects instantly, plus a per-project Postgres database with end-user auth. Generated artifacts are persistent, share-able via public links, and can be opened in the full Code Canvas workspace for terminal access, file tree editing, and multi-tab coding. **Examples:** “Build me a todo app with login”; “Add a leaderboard chart to this dashboard” **Also known as:** code mode, code artifacts ### Image Mode URL: https://opencharts.com/glossary/image-mode Definition: Image Mode generates and edits images from chat — pick aspect ratio, style, and brand palette, then iterate with restyle, upscale, and background-remove tools. Image Mode auto-routes between Theo Photo (photoreal), Theo Studio (illustrative), and Theo Type (typography-heavy) engines based on prompt content. Output is rendered as an image artifact card with edit, upscale, restyle, and remove-background actions. For richer compositions, switch to the Image Canvas — a node-graph editor where each node is an image step that can be tweaked or recombined. **Examples:** “Generate a cinematic poster”; “Turn this photo into a watercolor” **Also known as:** AI image, image generation mode ### Video Mode URL: https://opencharts.com/glossary/video-mode Definition: Video Mode generates short videos from a prompt — pick aspect ratio, duration, and visual style, then preview and share or download the result. Video Mode covers text-to-video and image-to-video flows with multiple aesthetics (cinematic, animated, watercolor, pixel art). Each output is a video artifact with preview, share, and download actions. For multi-segment narratives with storyboard editing and narration, see the Movies surface. **Examples:** “Make a 6-second hero video for our landing page” **Also known as:** AI video, text-to-video ### Voice Mode URL: https://opencharts.com/glossary/voice-mode Definition: Voice Mode is real-time, streaming audio chat with Theo — speak to brainstorm, dictate, get summaries, and trigger creation tools without typing. Voice Mode opens a low-latency audio session with Theo Voice. The mascot transforms into an orb that visualizes the live waveform, transcripts stream beneath it, and any creation tool you’d trigger via text (flowchart, notes, task) works the same way over voice. Voice Mode also powers Notes voice dictation and the Theo Desk hands-free agent loop. **Examples:** “Brainstorm a launch plan with me”; “Summarize my last meeting” **Also known as:** audio mode, Theo Voice ### Social & Calendar Mode URL: https://opencharts.com/glossary/social-mode Definition: Social Mode is Theo’s calendar-and-content-planning agent — it builds interactive HTML calendars, content schedules, Gantt timelines, and Kanban structure boards in one go. Social Mode runs a phase-aware execution flow: Phase A delivers a hero artifact (an interactive calendar), Phase B fans out supporting artifacts (Gantt timeline, Kanban board, content briefs). It uses brand-aware AI — point Theo at a URL and it pulls colors, fonts, and tone before producing the artifacts. **Examples:** “Build a content calendar for our Q3 launch”; “Plan a 4-week social schedule” **Also known as:** calendar mode, content mode ### Learn Mode URL: https://opencharts.com/glossary/learn-mode Definition: Learn Mode is an orchestrated study suite — pick a topic and depth, and Theo creates flashcards, a quiz, structured study notes, a presentation, and a knowledge map in parallel. Learn Mode is built for studying anything fast. Choose a depth (high-school, college, or deep dive), and a multi-agent pipeline produces a coordinated bundle of artifacts: flashcards (deck), quiz (multiple choice/true-false/fill-in-the-blank), structured study notes, a presentation, and a knowledge map. Sessions persist so you can resume, re-quiz yourself, or export the bundle. **Examples:** “Teach me the basics of Kubernetes”; “Make me a calculus crash course” **Also known as:** study mode, learning suite ### Consensus Mode URL: https://opencharts.com/glossary/consensus-mode Definition: Consensus Mode asks 7 different AI engines the same question, ranks their answers by agreement, and synthesizes a unified answer with a per-model breakdown card. Consensus Mode is the right tool when correctness is critical and you don’t want to bet on a single model. The Consensus Panel surfaces each engine’s response side-by-side, color-codes agreement, and a synthesis pass produces a final answer with caveats. **Examples:** “What’s the best way to architect this auth flow?”; “Settle a debate on RTO vs RPO targets” **Also known as:** multi-model mode, quorum mode ### Theo Stealth (Private Mode) URL: https://opencharts.com/glossary/stealth-mode Definition: Theo Stealth is the zero-retention private chat mode — ephemeral session, no history, no memory writes, and access to uncensored image and video engines. Stealth gives you an off-the-record session: messages aren’t persisted to your conversation history, no memories are written, and the surface uses a darker UI to make the mode obvious. Stealth also unlocks the Stealth Media Selector — a curated set of uncensored image and video engines for content that the default safety policies wouldn’t allow. **Examples:** Sensitive HR drafting; Private creative experimentation **Also known as:** private mode, off-the-record, dark room ### Theo (Chat Engine) URL: https://opencharts.com/glossary/engine-theo Definition: Theo is the default conversational engine — fast, capable, and tuned for everyday chat, drafting, and lightweight tool calling. Theo is the engine that powers Fast Mode and most casual conversations. It’s the cheapest option per request, sized for instant replies, and is the default for the dashboard sidebar mascot. Engine selection happens via the unified Theo catalog — never via raw provider IDs. **Also known as:** default engine ### Theo Pro URL: https://opencharts.com/glossary/engine-pro Definition: Theo Pro is the higher-quality conversational engine — used for hard reasoning, code, and modes where correctness and depth matter more than latency. Theo Pro powers Think Mode and the heavier paths in Code Mode and Research. It’s slower and more expensive than Theo, but produces tighter, better-cited, and better-structured outputs. **Also known as:** pro engine ### Theo Reason URL: https://opencharts.com/glossary/engine-reason Definition: Theo Reason is the deep-thinking engine — extended-deliberation reasoning for hard math, plans, and analysis tasks. Theo Reason powers Think Mode’s heaviest queries and is the engine used when correctness and stepwise rigor are non-negotiable. It trades latency for accuracy. **Also known as:** reasoning engine ### Theo Rapid URL: https://opencharts.com/glossary/engine-rapid Definition: Theo Rapid is the lightweight, ultra-fast engine used for autonomous skills, hooks, classifiers, and any background task where latency and cost matter more than depth. Rapid is the workhorse for background work — heartbeats, hook executions, intent scoring, classifier calls, telegram replies. It’s constrained to short generations and small step counts. **Also known as:** light engine, background engine ### Theo Photo URL: https://opencharts.com/glossary/engine-photo Definition: Theo Photo is the photoreal image engine — used for product shots, hero images, portraits, and anything that needs photographic fidelity. Photo is the auto-pick when prompts are photographic in nature. Image Mode and the Image Canvas route to Photo by default for realistic outputs, with Studio and Type as siblings for illustrative or typographic tasks. **Also known as:** photo engine ### Theo Studio URL: https://opencharts.com/glossary/engine-studio Definition: Theo Studio is the illustrative image engine — line art, painterly textures, brand-styled illustrations, and graphic design output. Studio is the auto-pick for non-photographic prompts (illustrations, vector-feel art, painterly compositions). It pairs naturally with the Image Canvas and presentations theming. **Also known as:** studio engine ### Theo Type URL: https://opencharts.com/glossary/engine-type Definition: Theo Type is the typography-aware image engine — used when prompts include readable text, posters, social tiles, and lettering-driven design. Type specializes in cleanly rendering on-image text — hard for general-purpose image models. It’s the auto-pick for posters, greeting cards, social tiles, and lettering-heavy layouts. **Also known as:** type engine ### Theo Voice URL: https://opencharts.com/glossary/engine-voice Definition: Theo Voice is the streaming audio engine — low-latency speech-to-speech that powers Voice Mode, Notes voice dictation, and the Theo Desk hands-free loop. Voice handles real-time turn-taking with sub-second latency, on-device-quality transcripts, and live interruption. It’s the same engine used everywhere voice is available across OpenCharts. **Also known as:** voice engine ### Theo Presenter URL: https://opencharts.com/glossary/engine-presenter Definition: Theo Presenter is the avatar-and-narration engine — used when a deck or movie needs a cinematic narrator and lip-synced presenter video. Presenter renders an avatar that narrates a script with synced mouth movement and natural prosody. It’s the engine behind narrated presentations, AI movies with hosts, and the Theo intro sequence. **Also known as:** presenter engine, avatar engine ### Consensus Panel URL: https://opencharts.com/glossary/engine-consensus-panel Definition: The Consensus Panel is the meta-engine behind Consensus Mode — it polls 7 different AI engines, scores agreement, and synthesizes a unified, sourced answer. The Consensus Panel runs every selected engine in parallel, normalizes their answers, and computes pairwise agreement. A synthesis pass then produces a final response with a per-model breakdown card so you can see where the engines diverged. **Also known as:** consensus engine, quorum panel ### Model Catalog URL: https://opencharts.com/glossary/model-catalog Definition: The Model Catalog is the single source of truth for every Theo engine — capabilities, credit cost, context window, fallback chain, sort order, and feature flags. Adding a new engine is a one-file change: append a ModelEntry to the catalog, register a provider adapter if needed, and ship behind a feature flag. Every dependent surface — credit accounting, context limits, consensus membership, image router, help docs — reads from the catalog automatically. User-visible naming follows a hard branding rule: only `Theo`-prefixed display names ever leave the server. **Also known as:** MODEL_CATALOG, Theo catalog ### Notes Editor URL: https://opencharts.com/glossary/notes-editor Definition: The Notes Editor is the OpenCharts rich-text workspace — a polished block editor with slash commands, themes, inline AI, version history, real-time collaboration, and exports to DOCX, PDF, Markdown, HTML, and JSON. Notes pairs a polished writing experience with the rest of the platform — every note can spawn a flowchart, a presentation, a podcast, or a movie from its content. Standard blocks (paragraphs, headings, lists, callouts, code, tables, images) sit alongside platform-specific blocks like webClip cards. Themes (Modern, Manuscript, Terminal, Focus, Notebook, Academic) change layout and typography; the AI side panel and inline AI handle generation and rewriting; tasks add structured checklists with priorities and due dates. **Examples:** Meeting notes you can convert into a follow-up deck; A research log with tasks and clipped sources **Also known as:** Notes, rich text editor, block editor ### Note Block URL: https://opencharts.com/glossary/note-block Definition: A note block is the atomic unit of a note — a paragraph, heading, list item, image, table, code block, callout, web clip, or task — each with its own ID, formatting, and slash-command shortcuts. OpenCharts Notes is built on a custom block editor. Every block has a stable ID so cross-block features like comments, tasks, and version history can pin to specific content. Custom block specs add platform features beyond the standard set — for example, the webClip block renders a collapsible card for clipped web content, with metadata, hover actions, and outline-sidebar integration. **Examples:** Heading + paragraph + bullet list; Embedded code block with syntax highlighting; Web clip card from the Chrome extension **Also known as:** block, note block ### Slash Command URL: https://opencharts.com/glossary/slash-command Definition: A slash command is a /-triggered menu inside Notes that inserts a block, runs an action, or opens an inline AI prompt — e.g. /heading, /todo, /clip, /ai. Type / anywhere in a note and a contextual menu appears with every block type, plus platform shortcuts: /clip to web-clip the current selection, /ai to summon inline AI, /task to insert a structured task, and more. Slash commands keep the editor keyboard-first and discoverable without cluttering the toolbar. **Examples:** /heading 1; /ai rewrite; /clip from URL **Also known as:** /-menu, block menu ### Notes Inline AI URL: https://opencharts.com/glossary/notes-inline-ai Definition: Notes Inline AI is the in-editor AI that lives on the toolbar and behind /ai — rewrite, continue, fix grammar, simplify, lengthen, or shorten any selection without leaving the document. Inline AI uses an in-editor AI streaming pipeline tightly integrated with the block editor. Edits land directly in the document with the changes highlighted, so you can accept or undo individual rewrites. Different from the Notes AI Side Panel — inline AI is fast and surgical; the side panel is conversational and document-aware. **Examples:** Highlight a paragraph → /ai shorten; Toolbar button → continue writing **Also known as:** inline editor AI, /ai ### Notes AI Side Panel URL: https://opencharts.com/glossary/notes-ai-panel Definition: The Notes AI Side Panel is a context-aware chat that sees the whole document — it can generate sections, summarize, expand, translate, organize, or pull facts from your notes. Open the side panel and Theo automatically reads the active note. From there you can chat to add new content, ask questions about what’s already there, or trigger quick-action templates (essay, meeting recap, brainstorm, study guide). Direct edits stream into the editor with highlighting; chat replies stay in the panel. Voice dictation is built in. **Examples:** “Summarize this page”; “Translate everything to Spanish”; “Expand section 2 into 3 paragraphs” **Also known as:** AI side panel ### Notes Themes URL: https://opencharts.com/glossary/notes-themes Definition: Notes themes are visual writing presets — Modern, Manuscript, Terminal, Focus, Notebook, and Academic — that change layout, typography, color, and even the available toolbar. Each theme retunes the writing surface for a specific use case: Manuscript for long-form prose, Terminal for code-heavy notes, Focus for distraction-free drafting, Notebook for sketchbook-style entries, Academic for citation-heavy writing. Themes affect rendering and tools, not stored content — switching themes never loses any blocks. **Examples:** Manuscript theme for a novel chapter; Terminal theme for a runbook **Also known as:** writing themes, note themes ### Notes Tasks URL: https://opencharts.com/glossary/notes-tasks Definition: Notes Tasks are structured to-dos that live inside notes — each task carries a priority, optional due date, and tiered automatic reminders. Tasks are first-class records: they’re queryable, can be tracked across notes, and trigger notifications and email/Telegram reminders as their due dates approach. They surface in the dashboard task widget and via Telegram. Tasks created from a clipped web article remember the source clip ID so you can jump back to the context. **Examples:** Urgent task with a 24h due date; Reminder for a meeting follow-up **Also known as:** task manager, to-do block ### Web Clipper URL: https://opencharts.com/glossary/web-clipper Definition: The Web Clipper is the OpenCharts Chrome extension that saves web pages, selections, highlights, screenshots, and images into Notes — with AI summarization, action extraction, and templated formatting. Five clip modes (full page readability, selection, highlight session, screenshot, image grab), plus AI-powered actions (summarize, extract action items, restyle as note). Destination picker lets you choose the project and the insertion position. Inside Notes, every clip becomes a webClip block — collapsible, with metadata header (URL, favicon, date) and outline-sidebar integration. Tasks and AI panels remain aware of the clip’s context. **Examples:** Clip a research paper into a study note; Highlight session across 5 articles **Also known as:** Chrome clipper, OpenCharts clipper ### Web Clip Block URL: https://opencharts.com/glossary/web-clip-block Definition: A web clip block is a special Notes block that renders a clipped web page or selection as a collapsible card with the source URL, favicon, clipped date, and re-clip / open / delete actions. Web clip blocks keep the original context attached to your notes. The metadata header makes provenance obvious; the outline sidebar lists every clip so you can navigate a research log quickly; AI tools can target only clip content when needed. **Examples:** Inline article card from the Chrome extension; Tweet clip with embedded media **Also known as:** clip block, webClip ### Flashcards URL: https://opencharts.com/glossary/flashcards Definition: Flashcards are AI-generated study cards from a note or a Learn Mode session — front-and-back deck with study and quiz modes, shareable via public links. Theo generates flashcards from your notes (or any topic in Learn Mode) and stores them as a deck artifact. Study mode flips cards; quiz mode supports multiple choice, true/false, and fill-in-the-blank. Decks are shareable — you can hand a teammate or student a public link with no signup required. **Examples:** Spanish vocab from a textbook chapter; Interview prep deck **Also known as:** study deck, flash deck ### Quiz URL: https://opencharts.com/glossary/quiz Definition: A quiz is an AI-generated test from a note or topic — multiple choice, true/false, and fill-in-the-blank questions with auto-grading and shareable links. Quizzes are first-class artifacts. Theo generates them from notes or Learn Mode sessions, you can take them inline, and the result is a graded score with per-question feedback. **Examples:** Mid-chapter check on a study note; Onboarding quiz for new hires **Also known as:** test, assessment ### Knowledge Map URL: https://opencharts.com/glossary/knowledge-map Definition: A knowledge map is an AI-generated mind-map-style breakdown of any topic — auto-saved as a Notes project for further editing or as part of Learn Mode and Explore Mode follow-ups. Knowledge maps cluster sub-concepts under a central topic and link them visually. They’re produced as part of Explore and Learn Mode, but you can also build one directly with the create_knowledge_map tool from chat. **Examples:** Concept map of distributed systems; Sub-topic breakdown of a course **Also known as:** concept map, topic map ### Notes Import URL: https://opencharts.com/glossary/notes-import Definition: Notes Import brings external content into OpenCharts — Markdown, HTML, Notion ZIPs, Obsidian vaults, and Evernote ENEX archives all convert into editable Notes. The importer preserves headings, lists, tables, code, frontmatter, internal links, and most embeds. Wiki-links from Obsidian rewrite to OpenCharts links; Notion exports keep their hierarchy. **Examples:** Migrate an Obsidian vault; Bring in 3 years of Evernote notes **Also known as:** import notes, note migration ### Notes Export URL: https://opencharts.com/glossary/notes-export Definition: Notes Export turns any note into Word (DOCX), PDF, Markdown, HTML, or JSON — with version history, snapshots, and Google Drive sync. Every note has full revision history; you can restore any prior snapshot or branch a new doc from one. Exports preserve themes when possible (DOCX styles, PDF typography) and Google Drive integration uploads exports directly to a folder. **Examples:** Submit a paper as DOCX; Snapshot before a major rewrite **Also known as:** export notes, version history ### Whiteboard URL: https://opencharts.com/glossary/whiteboard Definition: The Whiteboard is OpenCharts’ infinite, freeform canvas for sketching, sticky-noting, wireframing, and AI-assisted brainstorming — with hand-drawn aesthetics and a community component library. Whiteboards complement structured flowcharts: where a flowchart is a graph, a whiteboard is a canvas. Pen, pencil, eraser, shapes, sticky notes, and text live alongside the same node-based diagrams as the editor. AI Create, Edit, and Ask let Theo generate, modify, or query the canvas. Cross-mode conversion (structural or snapshot) turns whiteboards into flowcharts and vice versa. **Examples:** Sticky-note retro; Hand-drawn architecture sketch; Storyboard with a sticker palette **Also known as:** infinite canvas, freeform canvas ### Whiteboard Component Library URL: https://opencharts.com/glossary/whiteboard-component-library Definition: The whiteboard component library is a community-driven catalog of reusable shapes, UI kits, icons, and stencils that you can drag onto any whiteboard. Use the library for rapid wireframes, persona templates, retro frameworks, and architectural icon sets. Anyone can publish components for others to install. **Also known as:** component library, stencil set ### Whiteboard AI URL: https://opencharts.com/glossary/whiteboard-ai Definition: Whiteboard AI is the built-in assistant that can create, edit, or query whiteboard content — generate a retro template, restyle a sketch, or answer questions about what’s on the canvas. Three flows: AI Create generates new content from a prompt; AI Edit modifies a selection in place; AI Ask answers questions about the visible canvas. **Also known as:** whiteboard AI panel ### Cross-Mode Conversion URL: https://opencharts.com/glossary/cross-mode-conversion Definition: Cross-mode conversion turns a whiteboard into a flowchart (or vice versa) — either structurally (rebuilding nodes/edges) or via a high-fidelity snapshot. Structural conversion is the canonical path: it analyzes the source and rebuilds equivalent nodes and edges in the target. Snapshot conversion preserves the look exactly by embedding a rendered image. **Also known as:** mode conversion, whiteboard to flowchart ### Flowchart Canvas URL: https://opencharts.com/glossary/flowchart-canvas Definition: The flowchart canvas is the OpenCharts diagram editor where you build, drag, style, and connect nodes — with auto-layout, themes, history, comments, and live multiplayer. The canvas supports four core node types out of the box (terminal, process, decision, data) plus extended families (BPMN, swimlane, ERD, sequence) and stickers from Giphy. Drag and drop from the palette, double-click to edit labels, hold a connection point and drag to wire nodes. Auto-layout (top-to-bottom, left-to-right, radial, force-directed) is one click. Multi-select, copy/paste, snap-to-grid, alignment, undo/redo, and keyboard navigation are all standard. **Examples:** Drag a process box, label it, connect it **Also known as:** editor canvas, diagram canvas ### Node Palette URL: https://opencharts.com/glossary/node-palette Definition: The node palette is the side panel of available shapes you drag onto the canvas — terminals, processes, decisions, data, swimlanes, BPMN gateways, ERD entities, stickers, and more. Each palette entry is a registered node type with its own renderer. The palette is grouped (basic / BPMN / swimlane / data / extras) and searchable. Custom nodes added via templates show up automatically. **Also known as:** shape palette, shape library ### Auto Layout URL: https://opencharts.com/glossary/auto-layout Definition: Auto layout is the one-click cleanup that arranges your flowchart nodes — pick top-to-bottom, left-to-right, radial, or force-directed, and edges re-route automatically. Auto layout is great after extracting from a PDF/PPTX and after big edits. It preserves selection and respects swimlane lanes when present. **Also known as:** layout, auto-arrange ### Data Table URL: https://opencharts.com/glossary/data-table-block Definition: A data table is a spreadsheet-like grid attached to a flowchart node — with formulas (SUM, AVG, IF, VLOOKUP), conditional formatting, number formats, and CSV import. Data tables turn diagrams into living dashboards. Attach KPIs, owners, costs, or risk scores to nodes; sort and filter inline; export the table as CSV or include it in PDF/PPTX exports. **Examples:** RACI table on a swimlane node; KPI table on each VSM step **Also known as:** table block, spreadsheet block ### Templates Gallery URL: https://opencharts.com/glossary/templates-gallery Definition: The templates gallery is the OpenCharts catalog of starter projects — pre-built flowcharts, whiteboards, presentations, and notes you can clone with one click. Templates ship in 7+ categories (flowchart, process, decision, org, technical, business, research) and include both first-party and community-published packs. Users can publish their own templates and earn an Author Flair badge for popular ones. **Also known as:** template gallery ### Version History URL: https://opencharts.com/glossary/version-history Definition: Version history records every change to a project with the user, color, timestamp, and a human-readable summary — so you can see who did what and roll back any time. Every node add, edit, move, or bulk change is logged. Snapshots capture the full project state on demand. The history panel lets you browse, diff, and restore any past version, and granular undo can roll back individual changes. **Also known as:** history, revision history ### Share Link URL: https://opencharts.com/glossary/share-link Definition: A share link is a public URL that gives anyone with the link viewer, commenter, or editor access to a project — with optional expiration and password. Share links use a unique token, support all three permission levels, and can be revoked any time from the share dialog. Each access bumps an access counter for analytics. **Also known as:** public link, public share ### Permission Levels URL: https://opencharts.com/glossary/permission-levels Definition: Permission levels are the three sharing roles for projects — Viewer (read-only), Commenter (can add threaded comments), and Editor (full edit access). Permissions apply to email-based shares and public share links. Org membership has a separate, broader permission matrix (Owner / Admin / Editor / Viewer) for organization projects. **Also known as:** roles, share permissions ### Embedded Project Preview URL: https://opencharts.com/glossary/embedded-project-preview Definition: An embedded project preview is a miniature, read-only canvas render of a project that appears in forum posts, share pages, and external embeds. Previews live-update when the source project changes (subject to permissions) and have a hover zoom. Used by community showcases, the Fork & Remix workflow, and external embeds via /embed/[token]. **Also known as:** mini preview, live preview ### Fork & Remix URL: https://opencharts.com/glossary/fork-remix Definition: Fork & Remix copies someone else’s public project into your workspace — Fork makes a private copy, Remix copies and auto-creates a new community showcase post. The Use This and Remix buttons appear on every public showcase. Forks are private starting points; remixes maintain a remix-of relationship for credit. **Also known as:** use this, remix ### AI Extraction URL: https://opencharts.com/glossary/ai-extraction Definition: AI Extraction converts uploaded PDFs, PowerPoints, and images into editable flowcharts — Theo identifies nodes, edges, decision branches, and labels and applies auto-layout. Extraction routes through Theo's document parsing layer and the Theo image/text engines for structural analysis. Best results come from clean single-page documents; multi-page is supported but tends to be most accurate one diagram per pass. **Also known as:** PDF extraction, PowerPoint extraction ### Trash & Recovery URL: https://opencharts.com/glossary/trash-recovery Definition: Trash & Recovery is OpenCharts’ soft-delete system — deleted projects move to trash, are recoverable for 30 days, and can also be permanently deleted at any time. Deletes set a deletedAt timestamp; the trash view lists everything you’ve removed with a days-remaining counter. Restore replaces the project in its original folder; permanent delete purges blob and DB rows. Drafts also have a separate local-storage recovery path. **Also known as:** soft delete, recycle bin ### Folder URL: https://opencharts.com/glossary/folder Definition: Folders organize projects in your workspace — name, color, icon, nesting, drag-and-drop, starred, and a sidebar tree for fast navigation. Folders are personal-workspace primitives (separate from team projects). Starring a project pins it; the sidebar exposes the folder tree, recent files, starred, shared, and trash. **Also known as:** project folder ### Presentation Deck URL: https://opencharts.com/glossary/presentation-deck Definition: A presentation deck is an OpenCharts slide deck — AI-generated, theme-aware, with charts, animations, speaker notes, presenter view, rehearsal coach, and one-click web publishing. Decks support 8+ slide layouts, a rich element model (text, image, shape, code, list, icon, chart), AI backgrounds, custom themes, brand extraction, and a teleprompter/rehearsal flow. You can publish to the web with a custom slug, password, and SEO controls, or export to PDF/PPTX/PNG. **Also known as:** slide deck, deck ### Content Mode (Presentations) URL: https://opencharts.com/glossary/content-mode-deck Definition: Content Mode is the structured presentation builder — AI generates a clean outline-driven deck with strong typography and minimal visual flair, ideal for executive and technical decks. Content Mode is the right pick when the message matters more than the visuals. Compared to Creator Mode, it leans on layout, typography, and a quieter palette. **Also known as:** content presentation ### Creator Mode (Presentations) URL: https://opencharts.com/glossary/creator-mode-deck Definition: Creator Mode is the visual-first presentation builder — AI-generated images, illustrations, and photo backgrounds dominate the slides, ideal for marketing and conference decks. Creator Mode unlocks per-slide visual styles, AI background generation, and a heavier reliance on Theo Photo, Studio, and Type engines. **Also known as:** creator presentation, visual mode ### Slide Layout URL: https://opencharts.com/glossary/slide-layout Definition: Slide layouts are the canonical templates for individual slides — title, two-column, image-left, image-right, full-image, blank, section divider, and quote. Each layout is a starting point with anchored regions for text, images, charts, and shapes. You can override anything and the deck stays consistent across slides. **Also known as:** layout, slide template ### Speaker Notes URL: https://opencharts.com/glossary/speaker-notes Definition: Speaker notes are the per-slide notes that only you see during a presentation — visible in Presenter View and the Teleprompter, and editable from the deck editor. Theo can auto-generate speaker notes from slide content (concise or expanded), and the rehearsal coach uses them as the script for live grading. **Also known as:** presenter notes ### Presenter View URL: https://opencharts.com/glossary/presenter-view Definition: Presenter View is the dual-window mode that shows the audience the active slide while you see the next slide, speaker notes, a timer, and the AI cheat sheet. It’s the standard pro presenter setup — current slide, next slide, notes, timer — plus an OpenCharts-only cheat sheet that suggests follow-up bullets if you go off-script. **Also known as:** dual window mode ### Rehearsal Coach URL: https://opencharts.com/glossary/rehearsal-coach Definition: The Rehearsal Coach grades your delivery in real time — pacing, filler words, on-script accuracy — and produces a per-slide score and improvement notes. Talk through your deck with the coach on, and Theo listens via Theo Voice, transcribes, and compares against the speaker notes. You get an aggregated score and section-level feedback. **Also known as:** rehearse mode ### Teleprompter URL: https://opencharts.com/glossary/teleprompter Definition: The teleprompter scrolls your speaker notes in sync with your speech — Theo Voice tracks your words and advances the script automatically. Auto-scroll matches your pace; manual override is always available. Useful for conference talks, video shoots, and recorded narrations. **Also known as:** auto-scroll script ### Custom Theme Builder (Presentations) URL: https://opencharts.com/glossary/custom-theme-builder Definition: The Custom Theme Builder defines a brand-aware presentation theme — colors, fonts, dark mode, logo, logo placement — saved per user and applied to any deck. Themes pull in 1,500+ Google Fonts, support dark/light, primary and accent colors, mute/surface tokens, and an optional logo with placement. Brand Extraction can pre-fill all of this from a URL. **Also known as:** theme builder ### Brand Extraction URL: https://opencharts.com/glossary/brand-extraction Definition: Brand Extraction pulls colors, fonts, logos, and visual style from any URL via the Brand.dev API — used by the Custom Theme Builder and brand-aware Social Mode. Point at a URL and OpenCharts calls the Brand Retrieve and Styleguide APIs in parallel to assemble a coherent theme. The result is editable before you save it. **Also known as:** brand kit extraction ### AI Background URL: https://opencharts.com/glossary/ai-background Definition: An AI background is a per-slide generated image used as the slide’s backdrop — produced by Theo Photo or Studio with a prompt, then reused via Creator Mode visual styles. AI backgrounds work with any layout, are aware of the deck’s theme, and can be locked across slides for visual consistency. **Also known as:** AI slide background ### Charts in Presentations URL: https://opencharts.com/glossary/presentation-charts Definition: Presentation charts are interactive bar, line, pie, donut, area, scatter, radar, and histogram visualizations — with multi-series data, CSV/XLSX import, palettes, and animation. Charts are first-class slide elements. You can paste data, import CSV/XLSX, or generate with AI, then tune palettes, legends, and grid lines without leaving the slide. **Also known as:** slide charts ### Presentation Image Editor URL: https://opencharts.com/glossary/presentation-image-editor Definition: The presentation image editor crops, filters, annotates, frames, and adjusts images directly inside the slide editor — no round-trip to a separate tool. It’s a focused inline editor: crop and clip shapes, filter presets (grayscale, sepia, blur, vintage), shadows, polaroid frames, duotone, brightness/contrast/saturation/hue. Annotations stay editable. **Also known as:** image editor, slide image editor ### Publish to Web (Presentations) URL: https://opencharts.com/glossary/publish-to-web Definition: Publish to Web turns any deck into a hosted page — custom slug, password protection, SEO controls, favicon, background video, logo, and a QR code for live audiences. Publishing creates a permanent URL you can share with attendees, embed in newsletters, or hand to clients. Edits to the deck propagate to the published page on save (subject to publish toggle). **Also known as:** web publish, deck publish ### Flowchart URL: https://opencharts.com/glossary/flowchart Definition: A flowchart is a diagram that represents a process, workflow, or algorithm using shapes (nodes) connected by arrows (edges) to show the order of steps. A flowchart is the canonical visual format for documenting how something gets done. The standard shape vocabulary — terminal (oval) for start/end, process (rectangle) for actions, decision (diamond) for branches, and data (parallelogram) for input/output — has been used since the 1940s and remains the lingua franca for explaining processes to humans. In modern software, flowcharts are rendered as interactive directed graphs of nodes and edges with optional swimlanes, group containers, and labels on the connections. AI-native tools like OpenCharts can generate complete flowcharts from a PDF, prompt, or whiteboard sketch — turning unstructured documentation into editable, shareable, version-controlled diagrams in seconds. **Examples:** Customer onboarding for a B2B SaaS; Loan approval decision tree; Software deployment pipeline; Manufacturing quality control checklist **Also known as:** process flowchart, process diagram, flow diagram ### BPMN URL: https://opencharts.com/glossary/bpmn Definition: BPMN (Business Process Model and Notation) is a standardized graphical language for modeling business processes using pools, lanes, gateways, activities, and events. BPMN was created by the Object Management Group (OMG) and is the most widely-used formal notation for documenting business processes. Version 2.0 added a serialization format (BPMN XML) so models could be exchanged between tools and even executed by workflow engines. Where simple flowcharts use four shape types, BPMN distinguishes activities (rectangles), gateways (diamonds for branching/merging), events (circles for things that happen), and sequence/message flows (arrows). Pools represent organizations and lanes represent roles within them. OpenCharts supports BPMN-style notation as a first-class node family: pools, lanes, exclusive/parallel/inclusive gateways, start/intermediate/end events, and message flows. **Examples:** Order-to-cash with finance and fulfillment lanes; Hire-to-retire with HR, IT, and manager pools; Approval workflow with parallel reviewers **Also known as:** BPMN 2.0, Business Process Model and Notation ### Swimlane diagram URL: https://opencharts.com/glossary/swimlane Definition: A swimlane diagram is a flowchart that organizes activities into horizontal or vertical lanes, with each lane representing a different actor, role, or department responsible for those activities. Swimlane diagrams (also called cross-functional flowcharts) extend the basic flowchart by adding lanes that make ownership explicit. Every activity sits inside exactly one lane, and arrows that cross lanes are handoffs — usually the most important parts of the process to investigate. Common use cases include customer onboarding (Sales → Onboarding → Success), incident response (Detection → Triage → Resolution → Comms), and approval workflows (Requester → Reviewer → Approver → Finance). OpenCharts supports both horizontal and vertical swimlanes. AI generation places activities in the right lane automatically based on the actor described in your prompt. **Examples:** Cross-functional customer onboarding; IT change management; Procurement and approval workflow **Also known as:** cross-functional flowchart, Rummler-Brache diagram, deployment chart ### Decision tree URL: https://opencharts.com/glossary/decision-tree Definition: A decision tree is a tree-shaped diagram that maps a sequence of choices and their possible outcomes, used for decision support, classification, and policy documentation. Decision trees can be informal (a manager's playbook for handling support tickets) or formal (a machine-learning classification tree). The structure is the same: a root question, branches representing alternatives, and leaves representing outcomes or final classifications. Branches can be binary (yes/no), multi-way, or weighted by probability. Modern decision-tree tools attach metadata to each node — risk score, owner, regulatory note — so the tree doubles as policy documentation. OpenCharts AI builds editable decision trees from a question or policy document. Each node supports an attached data table for risk scores, owners, and notes, and the result can be published as a public share link or embedded in help docs. **Examples:** Loan approval flow; Customer support tier routing; Medical triage protocol; Eligibility checks for a benefits program **Also known as:** decision diagram, classification tree ### Mind map URL: https://opencharts.com/glossary/mind-map Definition: A mind map is a radial diagram that organizes information around a central idea, with primary branches for major themes and sub-branches for supporting details. Mind maps were popularized by Tony Buzan in the 1970s as a tool for thinking, learning, and brainstorming. The radial structure makes hierarchy visible at a glance and encourages free association: every node can spawn additional sub-nodes without disrupting the rest of the map. Common applications include lecture notes, meeting brainstorms, project planning, research outlines, and product roadmaps. Modern mind-mapping tools add image attachments, color-coded branches, and one-click conversion to other diagram types. OpenCharts AI generates editable mind maps from a topic, long note, or research document. Maps can be converted to flowcharts in one click and shared via public links. **Examples:** Project planning brainstorm; Research outline for a thesis; Product launch checklist; Meeting note structure **Also known as:** concept map, spider diagram, radial diagram ### ER diagram URL: https://opencharts.com/glossary/er-diagram Definition: An entity-relationship (ER) diagram is a data-modeling diagram that shows entities (database tables or objects), their attributes, and the relationships between them. ER diagrams are the foundational tool for designing relational databases. Entities are usually rendered as rectangles containing attributes; relationships connect entities with cardinality markers (1:1, 1:N, N:M). The classic notation is Chen's; modern tools use crow's-foot notation almost universally. Beyond databases, ER diagrams help document any domain model — a CRM's account/contact/opportunity hierarchy, an e-commerce catalog's product/variant/inventory model, or a content platform's post/author/comment graph. OpenCharts supports ERD-style nodes with attached attribute tables and crow's-foot relationship markers. AI generation can produce a draft ERD from a description of the domain. **Examples:** E-commerce product catalog; CRM data model; Booking system entities **Also known as:** entity-relationship diagram, ERD, data model ### Sequence diagram URL: https://opencharts.com/glossary/sequence-diagram Definition: A sequence diagram is a UML interaction diagram that shows how objects or actors exchange messages over time, with vertical lifelines and horizontal arrows. Sequence diagrams are the standard way to document an API call sequence, an authentication handshake, or any interaction where the order of messages matters. The Y-axis is time (top → bottom), the X-axis is participants (lifelines), and arrows are messages with optional labels and return values. Common patterns include synchronous calls (filled arrowhead), asynchronous calls (open arrowhead), self-calls (looping arrow back to the same lifeline), and activations (the rectangle on a lifeline that shows when an object is doing work). OpenCharts can model sequence diagrams using its structured node types — participant, message, return, and activation — with auto-layout that keeps lifelines aligned. **Examples:** OAuth 2.0 authorization code flow; Stripe checkout webhook flow; MCP client → server tool call sequence **Also known as:** UML sequence diagram ### UML URL: https://opencharts.com/glossary/uml Definition: UML (Unified Modeling Language) is a standardized family of diagrams used in software engineering to model systems, including class, sequence, activity, state, and use-case diagrams. UML was created in the 1990s by Grady Booch, Ivar Jacobson, and James Rumbaugh and standardized by the OMG. It groups diagrams into structural (class, component, deployment) and behavioral (use case, activity, state machine, sequence, communication) families. The notation is verbose but expressive enough to model an entire system. In practice, most teams adopt a small subset — usually class diagrams, sequence diagrams, and activity diagrams. Lighter-weight alternatives like C4 model are increasingly popular for documenting modern microservice architectures. OpenCharts supports the most common UML diagram types via structured node families and templates: class, sequence, activity, and state. Generation works from a code description or system context prompt. **Also known as:** Unified Modeling Language ### Org chart URL: https://opencharts.com/glossary/org-chart Definition: An organizational chart (org chart) is a tree-shaped diagram that shows a company's reporting structure, with employees as nodes and reporting relationships as edges. Org charts can be hierarchical (the classic top-down tree), matrixed (employees report to multiple managers), or flat (everyone reports to one or two leaders). Modern HR tools generate them automatically from the HRIS but the visual artifact is still essential for onboarding, planning, and external communication. Variants include hiring plans (open headcount overlaid on the existing structure), succession plans (next-in-line markers), and ICP/IC vs. manager splits (visualizing the dual-track career ladder). OpenCharts builds editable org charts from a CSV roster, directory PDF, or natural-language description. Each node supports headshots, role colors, attached data tables, and team grouping. **Examples:** Engineering org chart; Hiring plan with open headcount; Succession planning chart **Also known as:** organizational chart, organization chart, organogram ### Data flow diagram URL: https://opencharts.com/glossary/data-flow-diagram Definition: A data flow diagram (DFD) is a graphical representation of how data moves through a system, showing data sources, processes, data stores, and external entities. Data flow diagrams are the canonical way to document the data plane of a system. They distinguish between processes (circles or rounded rectangles) that transform data, data stores (open rectangles) that persist data, external entities (squares) that supply or consume data, and data flows (arrows) that connect them. DFDs are usually drawn at multiple levels — Level 0 (context), Level 1 (major processes), Level 2+ (decomposition). The Yourdon-DeMarco and Gane-Sarson notations are the most common. OpenCharts supports DFD-style nodes (process, data store, external entity, data flow) with auto-layout suitable for both context and decomposition diagrams. **Also known as:** DFD, data flow chart ### Network diagram URL: https://opencharts.com/glossary/network-diagram Definition: A network diagram is a visual representation of computer or organizational networks, showing devices (nodes) and the connections (edges) between them. Network diagrams come in two main flavors: physical (showing actual hardware — routers, switches, servers, firewalls) and logical (showing IP subnets, VLANs, security boundaries). They're essential for capacity planning, incident response, and compliance documentation. Variants include topology diagrams (star, mesh, tree, hybrid), Visio-style enterprise network maps, and cloud architecture diagrams (AWS VPC, GCP project graph). Larger networks benefit from layered diagrams with collapsible groups for each region or VLAN. OpenCharts supports network-diagram-style node types with custom icons, group containers for VLANs/subnets, and arrows for trust boundaries. **Also known as:** network topology diagram, infrastructure diagram ### State machine URL: https://opencharts.com/glossary/state-machine Definition: A state machine (or state diagram) is a diagram that shows the discrete states an object can be in and the transitions that move it between states, often with conditions or events on each transition. State machines are foundational to anything that has lifecycle: an order (created → paid → fulfilled → returned), a UI component (idle → loading → success/error), or a hardware device (off → standby → running). Formally, a state machine is a 5-tuple of states, alphabet, transitions, initial state, and accept states. Common variants include finite state machines (FSM), hierarchical state machines (Statecharts), and pushdown automata. Modern frontend tools like XState model UI as state machines for testability. OpenCharts supports state-diagram-style nodes (state, initial pseudo-state, final pseudo-state, transition) with labeled arrows. **Also known as:** state diagram, FSM, Statechart ### Gantt chart URL: https://opencharts.com/glossary/gantt-chart Definition: A Gantt chart is a horizontal bar chart that visualizes a project schedule, with tasks on the Y-axis and time on the X-axis, including dependencies and milestones. Gantt charts were popularized by Henry Gantt in the 1910s as a project-management visualization. Each row is a task with a start and end date; bars represent duration; arrows between bars show dependencies. Critical path analysis highlights the sequence of tasks that determines the project's earliest finish date. Modern Gantt tools blend traditional timelines with Kanban-style status, resource leveling, and dependency calculation. For SaaS launches and engineering roadmaps, a simplified Gantt with milestones and dependencies is usually enough. OpenCharts supports Gantt-style timelines via the AI Calendar Builder and a structured Gantt template family in the gallery. **Also known as:** project timeline, schedule chart ### Kanban board URL: https://opencharts.com/glossary/kanban Definition: A Kanban board is a visual workflow tool that organizes tasks into columns representing stages of work, used to manage flow, limit work-in-progress, and surface bottlenecks. Kanban (literally 'visual signal' in Japanese) was developed at Toyota and adapted for software by David Anderson. The core practice is to make work visible, limit work-in-progress (WIP), and pull new work only when capacity exists. Cards move left-to-right through columns like Backlog → To Do → In Progress → Review → Done. Modern Kanban tools layer on swimlanes (per team, per priority), WIP limits, cycle time analytics, and SLA-based escalation. For most teams, a clear three-column board (To Do / Doing / Done) with WIP limits is enough. OpenCharts ships a Kanban template family on the whiteboard that you can extend with custom columns, swimlanes, and AI-suggested next actions. **Also known as:** Kanban, task board ### Value stream map URL: https://opencharts.com/glossary/value-stream-map Definition: A value stream map (VSM) is a Lean diagram that captures the flow of materials and information for a product or service, used to identify waste and design improved future-state processes. Value stream mapping was developed at Toyota as part of the Toyota Production System and brought into the lean software movement by Mary and Tom Poppendieck. A VSM walks the entire process from customer request to delivery, marking process boxes with cycle time, lead time, and changeover, and identifying queues and waste. Software teams use VSMs to find DORA bottlenecks (lead time for change, deployment frequency), surface handoff delays, and design future-state CI/CD flows. OpenCharts supports VSM-style flowcharts with attached data tables for cycle time, lead time, and value-add ratio per step. **Also known as:** VSM, value stream mapping ### SWOT analysis URL: https://opencharts.com/glossary/swot Definition: A SWOT analysis is a strategic-planning framework that maps Strengths, Weaknesses, Opportunities, and Threats into a 2×2 matrix to support decision-making. SWOT was developed at the Stanford Research Institute in the 1960s and remains the most-used strategic planning tool. Strengths and Weaknesses are internal; Opportunities and Threats are external. Filling out the matrix forces a structured assessment of where to invest, what to defend, and what to watch. Modern variants extend the basic 2×2 with a TOWS matrix (matching internal factors to external ones for strategy), a SOAR (positive-only) variant, and PESTLE (political/economic/social/technological/legal/environmental) for the external scan. OpenCharts ships a SWOT template family with pre-laid-out 2×2 grids you can populate with AI suggestions or fill manually. **Also known as:** SWOT matrix, TOWS matrix ### Fishbone diagram URL: https://opencharts.com/glossary/fishbone Definition: A fishbone diagram (also called Ishikawa or cause-and-effect diagram) is a tool for root-cause analysis that organizes potential causes of a problem into categories radiating from a central spine. Fishbone diagrams were developed by Kaoru Ishikawa in the 1960s for quality control. The 'head' of the fish is the problem statement; the 'spine' runs horizontally; and the 'bones' represent categories of cause (the 6 M's: Manpower, Methods, Machines, Materials, Measurement, Mother Nature). The visual structure forces a team to consider every category before jumping to a single hypothesis. Variants include 5 Whys-anchored versions and Lean's 8-waste-anchored versions. OpenCharts supports fishbone-style diagrams via the whiteboard and a fishbone template that you can fill with AI-suggested causes from a problem statement. **Also known as:** Ishikawa diagram, cause-and-effect diagram ### Process map URL: https://opencharts.com/glossary/process-map Definition: A process map is a visual representation of a workflow that documents the sequence of steps, decision points, and handoffs needed to complete a business outcome. Process maps are the umbrella category that includes basic flowcharts, swimlane diagrams, value stream maps, BPMN models, and SIPOC charts. The level of formality varies — a quick whiteboard sketch is a process map, and so is a fully-attributed BPMN 2.0 model. Common applications include onboarding, fulfillment, support, audit, change management, and incident response. The discipline of process mapping reveals queues, redundant approvals, and informal handoffs that aren't visible in narrative SOPs. OpenCharts AI generates editable process maps from a description, SOP PDF, or PowerPoint slide. Each step supports an attached data table for cycle time, KPIs, owner, and notes. **Also known as:** business process map, process diagram, process flow ### RACI matrix URL: https://opencharts.com/glossary/raci Definition: A RACI matrix is a responsibility-assignment table that maps tasks to roles using four labels — Responsible, Accountable, Consulted, and Informed — to clarify who does what. RACI matrices are usually drawn as a grid with tasks as rows and roles as columns. Each cell contains R, A, C, or I. There must be exactly one A per task, and any row should usually have at least one R. The discipline forces a team to make ownership explicit and surfaces ambiguity early. Variants include RASCI (adds Support), DACI (driver, approver, contributor, informed), and RACI-VS (verifier, signatory). Choose the simplest variant your org will actually use. OpenCharts supports RACI matrices as data tables attached to flowchart or swimlane nodes, plus a standalone RACI table template in the gallery. **Also known as:** RACI chart, responsibility matrix ### Customer journey map URL: https://opencharts.com/glossary/customer-journey Definition: A customer journey map is a visual diagram that depicts a customer's interactions with a product or service over time, including their actions, thoughts, emotions, and pain points at each stage. Customer journey maps move beyond pure process diagrams by adding the human dimension. Most CJMs have rows for actions, thoughts, emotions, opportunities, and pain points; columns are stages of the journey (Awareness → Consideration → Purchase → Onboarding → Retention → Advocacy). Variants include service blueprints (which add backstage operations), as-is vs. to-be journeys, and persona-specific journeys. The artifact is most useful when it surfaces moments of truth where small UX changes have outsized impact. OpenCharts ships customer journey templates on the whiteboard and supports AI generation from a product description and persona. **Also known as:** CJM, user journey map, experience map ### User flow URL: https://opencharts.com/glossary/user-flow Definition: A user flow is a diagram that maps the steps a user takes through a product or service to accomplish a specific goal, including screens, actions, and decision points. User flows are the most common diagram in product design, sitting between high-level customer journey maps (which span days or weeks) and low-level interaction-level wireframes (which span seconds). A well-drawn user flow shows every screen, every action, every decision branch, and every error state. The most extractable user flows have one persona, one goal, and a clear start/end. For multi-persona or multi-goal flows, split into separate diagrams and link them. OpenCharts AI generates user flows from a product description and goal. Screens can have attached image mocks; the same canvas supports freehand wireframes alongside structured nodes. **Also known as:** user-flow diagram, task flow ### Wireframe URL: https://opencharts.com/glossary/wireframe Definition: A wireframe is a low-fidelity sketch of a digital interface that shows layout, structure, and content placement, intentionally stripped of color, typography, and visual polish. Wireframes sit between user flows and high-fidelity mockups in the design pipeline. The point of a wireframe is to defer aesthetic decisions and force critique of layout and information hierarchy. Boxes, lines, and grayscale fills do all the work. Common variants include hand-drawn wireframes (best for early iteration), wireframe libraries inside Figma/Sketch, and lightweight tools optimized purely for wireframing. Higher-fidelity intermediate stages — 'mid-fi' wireframes — add light typography and basic color. OpenCharts supports wireframing via the whiteboard's hand-drawn aesthetic and shape library, plus an Image Canvas for AI-generated mockups when fidelity needs to step up. **Also known as:** wire frame, skeletal layout ### Sitemap URL: https://opencharts.com/glossary/sitemap Definition: A sitemap is a hierarchical diagram of a website's pages and the navigation between them, used in information architecture, content audits, and SEO planning. Sitemaps come in two main flavors: visual sitemaps (the planning artifact — a tree of pages and sections) and XML sitemaps (the machine-readable file at /sitemap.xml that search engines crawl). They share the underlying structure but serve different audiences. Information architects use visual sitemaps to plan content hierarchy before any pages are designed. The exercise reveals duplicate pages, orphan pages, and gaps in coverage. OpenCharts supports visual sitemaps as flowchart-style trees with collapsible group containers per section. AI generation can propose a sitemap from a product description. **Also known as:** site map, site structure ### Infographic URL: https://opencharts.com/glossary/infographic Definition: An infographic is a visual representation of information, data, or knowledge designed to make complex content quickly understandable, often combining charts, icons, and short text. Infographics blend data visualization with editorial design. The best infographics tell a single, clear story — a step-by-step process, a comparison, a timeline, or a data narrative — with a strong visual hierarchy that draws the eye through the content. Common formats include statistical infographics (charts + commentary), informational infographics (process explanations), timeline infographics, comparison infographics, and how-to infographics. The medium is now common in social media, white papers, and product marketing. OpenCharts supports infographic-style layouts via the AI Presentations builder and the whiteboard's free-form layout, with AI-generated images and brand themes. **Also known as:** info graphic ### MoSCoW prioritization URL: https://opencharts.com/glossary/moscow Definition: MoSCoW prioritization is a project-management framework that classifies requirements into four buckets — Must have, Should have, Could have, and Won't have — to align scope on what's truly essential. MoSCoW was developed by Dai Clegg at Oracle UK in the 1990s and adopted as a core technique of the DSDM (Dynamic Systems Development Method) framework. The four labels force a team to make scope trade-offs explicit and surface low-priority items that might otherwise sneak into the build. MoSCoW is most useful at the start of a release cycle for backlog grooming and at the end for go/no-go decisions. The 'Won't have' category is critical and often skipped — being explicit about what's NOT in scope is the whole point. OpenCharts ships MoSCoW templates as 4-quadrant whiteboards and supports AI-assisted classification of a backlog list. **Also known as:** MoSCoW method, MoSCoW analysis ### OKRs URL: https://opencharts.com/glossary/okr Definition: OKRs (Objectives and Key Results) is a goal-setting framework where each high-level Objective is paired with 2–5 measurable Key Results, used by Google, Intel, and many modern companies to align focus across teams. OKRs were popularized by Andy Grove at Intel and brought to Google by John Doerr. The Objective is a qualitative aspiration; Key Results are quantitative measures of progress. Setting OKRs is annual or quarterly; reviewing them is typically weekly or bi-weekly. A good Key Result is graded on a 0.0–1.0 scale where 0.7 is the target — meaning OKRs should be ambitious enough that consistently hitting 1.0 indicates the goals were too easy. OKRs are explicitly NOT compensation tools. OpenCharts supports OKR planning as flowchart-style trees (Company → Team → Individual) with attached data tables for KR progress, plus AI-assisted draft generation from a strategy doc. **Also known as:** Objectives and Key Results ### Persona URL: https://opencharts.com/glossary/persona Definition: A persona is a fictional but research-grounded archetype of a target user, used in product design and marketing to align teams on who they're building for and why. Personas were popularized by Alan Cooper in the 1990s and remain a foundational design artifact. A typical persona includes demographics, goals, motivations, frustrations, behaviors, and a quote that captures the archetype's voice. Personas should be built from real research (interviews, surveys, analytics) — fabricated personas can do more harm than good. Most teams need 3–7 personas; more than that and they stop being memorable. OpenCharts ships persona templates on the whiteboard with structured fields for demographics, goals, frustrations, and quotes, plus AI-assisted draft generation from interview notes. **Also known as:** user persona, buyer persona ### Retrospective URL: https://opencharts.com/glossary/retro Definition: A retrospective (or retro) is a structured team meeting at the end of an iteration where the team reflects on what went well, what didn't, and what to change next time. Retros are central to Agile and Lean practices. The most common formats include Start/Stop/Continue, 4 L's (Liked, Learned, Lacked, Longed for), Mad/Sad/Glad, and the sailboat (winds, anchors, rocks, sun). A good retro has a clear timebox, an owner, action items with assignees and deadlines, and a follow-up at the next retro to verify previous actions actually happened. Without follow-through, retros become venting sessions. OpenCharts ships retro templates on the whiteboard for every common format, plus AI-assisted summarization of sticky-note clusters into themes and action items. **Also known as:** retrospective meeting, sprint retro, post-mortem ### User story map URL: https://opencharts.com/glossary/story-map Definition: A user story map is a 2D arrangement of user stories where the X-axis is the user's journey and the Y-axis is priority, used to plan releases and surface feature gaps. Story mapping was developed by Jeff Patton as a corrective to flat backlog lists. The horizontal axis traces a user's narrative end-to-end (browse → add to cart → checkout → confirmation); the vertical axis stacks stories by release or priority. The result is a 2D map where you can slice horizontally to define a release scope. The technique is especially good at revealing missing stories — gaps in the journey that a flat backlog hides. OpenCharts supports story maps on the whiteboard using sticky-note-style nodes plus group containers for releases. AI-assisted generation from a product description proposes a starting map you can refine. **Also known as:** story mapping ### System context diagram URL: https://opencharts.com/glossary/system-context Definition: A system context diagram is a high-level architecture diagram that shows a system as a single box at the center, surrounded by the people and external systems it interacts with. System context diagrams are the top level of the C4 model (Context, Container, Component, Code) and the simplest useful architecture artifact. They make the system's boundary explicit — what's inside the box, what's outside, and which external integrations matter. Variants include the basic C4 context (the system + actors + external systems), enterprise-context diagrams that nest multiple systems, and threat-modeling context diagrams that highlight trust boundaries. OpenCharts supports C4-style context, container, and component diagrams via structured node types and templates, plus AI generation from a system description. **Also known as:** C4 context diagram, context diagram, boundary diagram ### HubSpot Integration URL: https://opencharts.com/glossary/integration-hubspot Definition: The HubSpot integration connects your CRM to Theo — manage contacts, deals, companies, and pipelines from chat or autonomous flows.

Membership uses OpenCharts' team-membership system behind the scenes; permissions are governed by the organization role matrix. Personal workspace and team workspaces are isolated and switchable from the dashboard tab strip. **Examples:** Your company tenant; A client workspace shared with collaborators **Also known as:** team, tenant, workspace ### Org Role URL: https://opencharts.com/glossary/org-role Definition: Org roles are the four permission tiers inside an organization — Owner, Admin, Editor, Viewer — that gate access to settings, members, projects, and chat. Owner is the billing contact and can transfer ownership; Admin manages members and settings; Editor can create/edit team projects and chat; Viewer is read-only. The exact permission matrix lives in `src/lib/organizationPermissions.ts` and powers the `canPerform()` hook. **Also known as:** organization role ### Team Chat URL: https://opencharts.com/glossary/team-chat Definition: Team Chat is the real-time messaging surface inside every organization — channels and DMs with presence, typing indicators, and emoji reactions. Each organization has a default channel and you can create more for projects, topics, or sub-teams. Token-based auth scopes the messaging connection per session; messages render with safe escaping; reactions, mentions, and notifications are first-class. **Also known as:** org chat, team messaging ### Team Channel URL: https://opencharts.com/glossary/team-channel Definition: A team channel is a topic-scoped thread inside an organization’s chat — pin announcements, share project updates, and tag teammates with @ mentions.

Webhooks keep your subscription state in sync in real time. **Also known as:** subscriptions, payments ### Code Canvas URL: https://opencharts.com/glossary/code-canvas Definition: Code Canvas is OpenCharts’ in-browser coding workspace — live in-browser preview, multi-file editor, terminal, file tree, AI iterations, and a per-project Postgres database. Code Canvas is where Theo-generated code projects live. The web version provides a live in-browser preview, a code editor, runtime error surfacing, and a “Try-to-fix” one-click repair flow. The desktop (Theo Desk) version adds a real PTY terminal, a multi-tab file tree, a syntax-highlighting code editor, and a local working directory mirrored to disk. Every project optionally enables a managed Postgres database with per-project credentials, SDK helpers (window.__db, window.__auth), and an end-user auth surface — so AI-built apps can ship with real persistence and login. **Examples:** A todo app with login; A leaderboard with real-time data **Also known as:** Code workspace, Theo Code Canvas ### Code Canvas Database URL: https://opencharts.com/glossary/code-canvas-database Definition: The Code Canvas Database is a managed per-project Postgres instance — accessible from generated apps via window.__db, with end-user auth, seeds, CSV import, schema history, and one-click revert. Each Code Canvas project can enable a live Postgres database. AI-generated app code can call window.__db.query for SQL and window.__auth.signup/login/logout for end-user authentication, all guarded by row-level security and a restricted public-query proxy. Theo can create and seed tables, scope rows to the current end user, import CSV, and revert any DDL via the schema-history collection. Storage quotas are plan-based. **Examples:** Add a users table with auth; Seed a contacts table from CSV **Also known as:** window.__db, code project DB ### Try-to-Fix URL: https://opencharts.com/glossary/try-to-fix Definition: Try-to-Fix is the one-click repair button in Code Canvas — when runtime errors appear, it sends the last 20 errors back to Theo to patch the code automatically. A red banner appears whenever the runtime error buffer collects new failures. Hitting Try-to-Fix builds a focused iterate prompt (with the deduped error summary) so Theo edits the affected files in place. Often resolves runtime crashes without a full conversation. **Also known as:** fix it, auto repair ### Code Share Artifact URL: https://opencharts.com/glossary/code-share-artifact Definition: A code share artifact is a public link to a Theo AI code project — recipients see a live preview, an HTML render, and the source files, no signup required.

Open the hub to see every episode, sort by date, group into collections, and grab a public player link. Episodes have cover art, transcripts, and metadata for embedding. **Also known as:** podcast library ### Podcast Collection URL: https://opencharts.com/glossary/podcast-collection Definition: A podcast collection is a curated bundle of episodes — your own podcast “show” with a shared cover art, description, and shareable show URL. Group related episodes into a collection to publish them as a series. Each collection has its own cover art and public landing page. **Also known as:** podcast show ### Cover Art URL: https://opencharts.com/glossary/cover-art Definition: Cover art is the AI-generated image that represents a podcast episode or collection — automatically created during generation and editable from the hub. Cover art uses the Theo image engines and respects a podcast’s topic and tone. You can re-roll, restyle, or upload your own from the hub. **Also known as:** episode cover, podcast art ### Theo Movies URL: https://opencharts.com/glossary/movie Definition: Theo Movies are multi-segment AI videos with a storyboard preview, narrated voiceover, and a polished final render — generated from notes or a prompt. Movies are the long-form sibling to Video Mode.

Visual styles include cinematic, animated, watercolor, pixel art, and more. **Examples:** Founder narrative for a launch; Concept explainer with hosts **Also known as:** AI movie, Theo movie ### Storyboard Preview URL: https://opencharts.com/glossary/storyboard-preview Definition: A storyboard preview is the editable scene-by-scene plan Theo produces before rendering a movie — review and tweak each shot before committing to the full render. Storyboards expose Theo’s plan: per-segment image, narration text, duration, and transition. Editing a segment re-renders only that part of the movie. The Review & Generate button locks in the final render. **Also known as:** movie storyboard, scene plan ### Visual Style URL: https://opencharts.com/glossary/visual-style Definition: A visual style is a prompt-and-engine preset that controls the aesthetic of generated media — cinematic, animated, watercolor, pixel art, and more — used by movies, presentations, and Image Canvas. Visual styles are reusable across surfaces. Pick one in Creator Mode and a deck adopts it across slides; pick one when generating a movie and every segment respects it. **Also known as:** aesthetic, style preset ### Background Removal URL: https://opencharts.com/glossary/background-removal Definition: Background removal is the one-click image action that cuts out the subject and produces a transparent PNG — usable on flowcharts, slides, and notes. Triggered from the image-action menu or via the bg-remove tool. Works on AI-generated and uploaded images, and the result drops back into the canvas, deck, or note in place. **Also known as:** bg remove, cutout ### Image Upscale URL: https://opencharts.com/glossary/image-upscale Definition: Image upscale increases an image’s resolution while preserving detail — useful for export-quality hero shots, posters, and prints. Run from the image-action menu or via the image-upscale tool. The Image Canvas exposes upscale as a node so you can branch a low-res draft and a high-res final without losing the original. **Also known as:** upscale, super-resolution ### E.V.I. (Executable Visual Intelligence) URL: https://opencharts.com/glossary/evi Definition: E.V.I. (Executable Visual Intelligence) is the OpenCharts pipeline runtime — turn any flowchart into a live AI workflow where Theo executes each node in real time, calls APIs, and produces real deliverables. Most flowcharts are static documentation; E.V.I. makes them executable. Every node maps to a Skill — a concrete behavior like “analyze this data,” “send an email,” or “create a presentation.” Click Run with Theo and Theo walks each node in order, passing data along, lighting up the canvas as it goes. E.V.I. is also an open protocol: flows are exportable as `.evi.json` and runnable by any compatible runtime. The pre-flight clarification pass collects any missing inputs before execution, and Human Gates pause the flow for approvals. The user’s “EDI” shorthand for this concept and the official E.V.I. acronym refer to the same system. **Examples:** Lead-intake → AI triage → Slack handoff; RFP draft → human approval → email send **Also known as:** EDI, Executable Visual Intelligence, Execution Canvas ### Execution Canvas URL: https://opencharts.com/glossary/execution-canvas Definition: The Execution Canvas is the live view at /editor/[id]?mode=live — a flowchart editor that lights up in real time as Theo runs each node, with logs, outputs, and an inspect panel. Four areas: Toolbar (Run/Stop, Test, validation, progress, history), the canvas itself with per-node state colors, an Inspect panel for outputs and AI reasoning, and an execution log timeline. Node states: Idle, Running (yellow), Completed (green), Failed (red), Waiting (blue, paused at a Human Gate). **Also known as:** live mode, EVI canvas ### Skill URL: https://opencharts.com/glossary/skill Definition: A skill is an installable extension that gives Theo a new behavior — a domain prompt, custom tools, allowed base tools, and an optional trigger (manual, event, schedule, or keyword). Skills extend Theo without modifying the core. Each skill ships with a system prompt extension, custom tool definitions, required base tools, and a trigger type. Install from the Skill Store or author your own; user-installed skills run with credit guards and a separate autonomous daily cap. Skills can power chat, scheduled background actions (via the heartbeat), event-driven hooks, and multi-step workflows. **Examples:** Content Calendar Builder skill; Daily Standup Summarizer skill **Also known as:** Theo skill, skill plugin ### Hook URL: https://opencharts.com/glossary/hook Definition: A hook is an event-driven trigger that runs Theo automatically when something happens — a project is created, a share is accepted, a task goes overdue, a forum reply lands. Hooks fire on platform events (share.accepted, task.overdue, project.created, team.member_joined, forum.post_replied). Each hook has a cooldown, a per-hook prompt template, credit guards, and an audit log. Hooks are opt-in and can be disabled per user or globally. They share the autonomous daily cap with skills and workflows. **Examples:** Share-accepted welcome message; Task-overdue summary **Also known as:** event hook, Theo hook ### Workflow URL: https://opencharts.com/glossary/workflow Definition: A workflow is a multi-step automation — tool calls, AI transforms, conditions, delays, and notifications wired together with branching logic and credit checkpoints. Workflows compose 5 step types (tool_call, ai_transform, condition, delay, notification) into a directed graph with onSuccess/onFailure branches. They can be triggered manually, on a schedule, on an event, or via webhook, and run with a strict step cap, a max-runtime budget, and auto-disable after consecutive failures. Author workflows from chat with the create_workflow tool, or from the workflows page. Run history is preserved per workflow. **Examples:** Daily research → summarize → email; Form submitted → enrich → CRM upsert **Also known as:** Theo workflow, automation ### Heartbeat URL: https://opencharts.com/glossary/heartbeat Definition: Heartbeat is Theo’s background loop that periodically evaluates your installed scheduled skills and workflows — checking their schedule, your quiet hours, and credit availability before running. The heartbeat runs every 30 minutes by default (per-user configurable), respects quiet hours and timezones, enforces the autonomous daily cap, and limits each cycle to one autonomous action per user. It’s opt-in: you control whether Theo runs in the background and can pause it any time. **Also known as:** background loop, scheduler ### Human Gate URL: https://opencharts.com/glossary/human-gate Definition: A human gate is a node in an E.V.I. flow that pauses execution and waits for an explicit accept/reject from a human — usually delivered as a Telegram or email approval prompt. Use human gates anywhere a flow shouldn’t auto-fire — sending an external email, charging a customer, posting publicly. The flow stays in Waiting state until someone hits Accept or Reject. Telegram’s inline-keyboard callback queries make approvals one-tap. **Examples:** Wait for Approval node before email send **Also known as:** approval gate, wait for approval ### .evi.json URL: https://opencharts.com/glossary/evi-json Definition: `.evi.json` is the open file format for E.V.I. flows — exportable from any flowchart and re-runnable on any compatible runtime. The format describes nodes, skills, edges, configuration, and policy. It’s designed to be portable so flows can move between OpenCharts and other E.V.I.-compatible runtimes — including future on-prem or self-hosted runners. **Also known as:** EVI JSON, evi.json ### Trigger URL: https://opencharts.com/glossary/trigger Definition: A trigger is the rule that decides when a skill, hook, or workflow runs — manual (you click Run), schedule (cron-like), event (platform event), or keyword (message match). Triggers are declared on each automation. Manual triggers wait for explicit invocation; scheduled triggers fire via the heartbeat; event triggers fire when matching platform events occur; keyword triggers fire when chat messages match defined patterns. **Also known as:** trigger type ### Run with Theo URL: https://opencharts.com/glossary/run-with-theo Definition: “Run with Theo” is the button at the top of any flowchart that hands the flow over to E.V.I. — Theo configures each node, validates the graph, and executes it on the Execution Canvas. Click the button (or use the ⋯ menu) and a cinematic transition takes you to the Execution Canvas. Theo reads each node label, infers the right skill, asks any clarifying questions, validates the graph, and runs. **Also known as:** go live, deploy flow ### Calendar Builder Skill URL: https://opencharts.com/glossary/calendar-builder-skill Definition: Calendar Builder is a built-in keyword-triggered skill that produces interactive HTML calendars — content calendars, posting schedules, project Gantts, and event timelines. Two flavors are bundled: content-calendar-builder and interactive-calendar-builder. Both run in two phases — Phase A is the hero artifact (interactive HTML calendar), Phase B is supporting artifacts like a Gantt timeline, Kanban structure board, and content briefs. **Also known as:** calendar skill ### Interactive Calendar URL: https://opencharts.com/glossary/interactive-calendar Definition: An interactive calendar is the HTML/CSS/JS calendar artifact produced by Social Mode — clickable, editable in chat, and shareable as a public page. Theo generates an interactive calendar inline (Phase A of Social Mode), which you can edit by chatting with Theo or by following up with “Phase B” to fan out a Gantt timeline, Kanban board, and content briefs. **Also known as:** HTML calendar, calendar artifact ## MCP Server — Full Reference OpenCharts provides a public MCP (Model Context Protocol) server so AI tools (Warp, Claude Desktop, Cursor, VS Code, Windsurf) can read and write OpenCharts artifacts directly. ### Server Details - Endpoint: `https://www.opencharts.com/api/mcp` - Transport: Streamable HTTP (POST only; GET returns 405) - Authentication: Bearer token via `Authorization` header - Rate limit: 120 requests/minute per user - Documentation: https://www.opencharts.com/help/mcp-server - API key management: https://www.opencharts.com/skills?view=mcp ### Authentication 1.
