Launched this week
Brainio turns every note into a visual mind map. Write in Markdown, press Tab to indent and create branches, switch between text, split, and mind map views with one click.
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! ๐
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 โ 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?
@ondrej_havlenaย Hey, I just want to say that I got the email that you guys redesigned your product, and I've been playing around with it for a couple minutes now. You have truly put together an exceptional redesign. I'm very impressed.
I will keep playing around with it and give you my thoughts, but so far I find it one of the easiest, if not the easiest, mind mapping products I've ever used. I think it's actually really cool because I think visually, so working on my project is going to help me a lot to organize my thoughts.
I'll let you know how I do with it.
