One conversation. Every canvas.

Theo is the AI orchestrator that powers every part of OpenCharts. It creates flowcharts, whiteboards, notes, presentations, podcasts, videos, code apps, and images from plain-language descriptions. Theo has 11 specialized modes optimized for different types of tasks: from instant answers (Fast) to deep research with citations (Research) to full app generation (Code) to private conversations (Stealth).

Theo has 11 modes: Fast (instant answers), Think (extended reasoning), Image (9 AI models), Video (5 AI models, text-to-video and image-to-video), Deep Research (web research with 20+ sources and citations), Voice (real-time spoken conversations), Code (full-stack app generation with live preview), Learn (Socratic teaching, flashcards, quizzes), Explore (broad discovery with web search), Consensus (cross-validated answers with confidence breakdowns), and Social Media (interactive content calendars and planning).

Yes. Theo is included in every OpenCharts plan, including the free tier. All 11 modes and all 8 canvas types are available. Generation uses AI credits, which are included in all plans. No credit card required to get started.

Yes. Theo is an orchestrator: a single conversation can produce flowcharts, presentations, notes, whiteboards, videos, code apps, images, and more. Theo intelligently picks the right canvas and tools for each part of your request.

Theo Stealth is a completely private, zero-retention AI mode. Messages are processed by a zero-retention provider and deleted instantly; nothing is stored in any database. Sessions exist only in your browser tab and vanish when you close it. Stealth includes unrestricted chat, 9 image models, 5 video models, and private web search.

Theo Research performs multi-step web research autonomously. It searches multiple engines, reads 20+ full source pages per query, cross-references findings, and compiles everything into a polished research report with inline citations, charts, and a bibliography.

Yes. Theo Video mode supports 5 AI models for text-to-video and image-to-video generation. Describe a scene and Theo writes a storyboard, generates each scene, and composites a finished video. Choose from Explainer, Cinematic, Whiteboard, or Animation styles in landscape (16:9) or portrait (9:16).

Yes. Code Canvas is a full-stack AI IDE in your browser. Describe an app (a landing page, a dashboard, a game) and Theo writes the code, shows a live preview, and lets you iterate through chat. Click any element in the preview to edit it visually. Deploy to a cloud sandbox with one click.

The Autonomy Layer has four tiers. Skills are modular capabilities you install (25+ built-in). Heartbeats run scheduled checks every 30 minutes. Hooks trigger actions on events (e.g., task overdue). Workflows chain multi-step automations with tools, AI transforms, conditions, and notifications. All actions are credit-guarded and auditable.

Yes. Theo builds a personal knowledge graph from your conversations. It remembers your preferences, project history, communication style, and domain context. Memory uses vector-powered semantic retrieval and behavioral pattern learning to make Theo more helpful over time. Memory is disabled in Stealth mode.

Theo Image mode includes 9 branded models: Theo Turbo (fast), Theo Core (balanced), Theo Ink (artistic), Theo Lucid (surreal), Theo Chroma (vivid), Theo Unbound (photorealistic), Theo Raw (uncensored SDXL), Theo Dream (cinematic), and Theo Dream Lite (fast cinematic). All support 4 aspect ratios.
