Hey everyone 👋

I built Rook because I wanted a place to take code notes for things like commands, snippets, configs, and AI outputs, and nothing existing fit that well.

I usually defaulted to Apple Notes since it’s fast and local, but it doesn’t support code blocks. Today, with AI in coding, I realized I needed more space for notes around what I was building.

When working with AI, there is often a high degree of cognitive offloading, where too much of the thinking gets externalized into tools and generated output. That output tends to be transient, useful in the moment but not always revisited or effectively lost after a session.

Rook is my attempt to build a notes app for the AI-native coding era, where that cognitive context can be captured and revisited in a single dedicated place for code notes.

It works whether you’re coding traditionally or using AI tools. You can optionally connect AI clients via MCP so they can write directly into it instead of copy-pasting.

Rook is free, fully native on Mac, offline by default, and everything stays on your machine. The MCP server is also open source.

Rook is completely free, and the first 100 people who sign up today will get a special lifetime discount as part of the Product Hunt launch.

Would love to hear feedback and any feature requests!
