Swimlane diagrams with AI
OpenCharts is an AI swimlane-diagram builder that turns a cross-functional process description into an editable swimlane (cross-functional flowchart) in seconds. Theo identifies actors and roles, assigns activities to lanes, and lays out handoffs cleanly. 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.
What you get
- 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
Frequently asked questions
Can OpenCharts auto-assign steps to lanes?
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.
Are vertical swimlanes supported?
Yes. Switch between horizontal and vertical orientations via the layout toolbar.
Can I attach KPIs to each step?
Yes. Every node supports an attached data table — perfect for SLAs, owners, KPIs, and process documentation.
Can swimlane diagrams export to PowerPoint?
Yes. Export as fully editable PPTX, plus PDF, PNG, SVG, DOCX, XLSX, and JSON.
Is this BPMN-compliant?
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.
