Show HN: Brainio – Markdown notepad that turns notes into visual mind maps (brainio.com)

This is really cool! What's your inspiration in building this?

amazing job with the text editor! feels good/easy to work with and format! did you code (or vibe i dont care) from scratch or used a library?

I noticed you switched from paid to free? What was behind that decision?

I’m very interested in Markdown related tools, I’m building one myself [1]. How have you found working with the MCP? I went for a CLI tool myself. Have you found that agents have produced anything interesting being able to link documents? /create maps?

nice man thats such a cool concept

Looks nice!

How does this compare to something like Logseq or Obsidian with a graph view? What's the main reason to switch?

Can I import my existing Markdown files? I have about 500 notes in Obsidian and I'd like to try this without starting from scratch.

I've been looking for a good MCP-enabled note taking app. What can Claude actually do with the 17 tools? Can it create a full mind map from a prompt?

Interesting approach. How does the Yjs sync work when two people edit the same node in the mind map view? Do you handle conflicts at the node level or at the text level?

How do you handle performance with large documents? I tend to write really long notes with 200+ nodes. Does the mind map view slow down at that scale?
