Built-in knowledge graph shows how all your documents connect. Collaborate in real time with live cursors. Link documents with bidirectional backlinks. Connect your AI assistant via MCP.
We launched Brainio 5 years ago. We rebuilt it from scratch and made it completely free. No document limits, no paywalls.

Hey PH! π
Ondrej here, co-founder of Brainio.
We've been building Brainio for 5 years. The idea has always been simple: your notes shouldn't be flat text. Every note in Brainio is also a visual mind map.
We just rebuilt it from scratch and made it completely free. No document limits, no paywalls.
Here's what you can do with it:
- Write in Markdown, switch to a mind map view with one click
- See how all your documents connect in a knowledge graph
- Collaborate in real time with live cursors
- Connect it to Claude, ChatGPT, or Cursor β Brainio has a built-in MCP server
- Use it on web or desktop (macOS, Windows, Linux)
What's next: mobile app, canvas/sketchpad, team spaces.
We'd love to hear what you think. What features matter most to you?
