Rook: Notes app for code. Claude, Cursor, and Gemini can save directly to it
Hey everyone 👋
I built Rook because I couldn't find a place for my code notes. I've been used to Apple Notes, it’s fast and minimal, however it doesn't support code blocks.
Why not use something that exists? I tried:
VS Code. It works for markdown, but I always needed a preview extension to see md files rendered, which felt clunky. And I wanted notes to live outside of any specific codebase, not tied to a repo. Something small, open on the side of my desktop.
Obsidian. Didn't feel right at all. Not designed for the kind of simplicity I was looking for.
Bear, Craft, Notion. Too clunky. Not as minimal or fast as I wanted.
Dedicated snippet apps. Opposite problem. Great for code, no place for the notes around it.
On top of that, coding with AI has multiplied my work and I found myself lacking a dedicated place to capture the ongoing logic.
So I built Rook. It’s a free, local and native Mac app made for code notes:
- markdown support
- syntax highlighted code blocks (17+ languages)
- 5 simple themes
- everything stays on your Mac
- optional MCP support so AI tools can write directly into it
I now just say “save this to Rook” to Claude instead of copy-pasting around.
