Mind maps with AI
OpenCharts is an AI mind-map maker that turns a topic, long note, or research document into an editable radial mind map in seconds. 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.
What you get
- 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
Frequently asked questions
Can I generate a mind map from a long note?
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.
Is the mind map editable?
Yes. The output is a fully editable React Flow canvas with all OpenCharts tools (themes, comments, multiplayer, export).
Can I convert a mind map to a flowchart?
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.
How big can a mind map get?
Maps with 200+ nodes work well. For larger maps, use group containers to collapse sub-trees and keep navigation snappy.
Is this free?
Yes. Mind map generation, themes, real-time collaboration, and export are included on every plan including the free tier.
