Typeset.md

A native macOS reader for Markdown. Double-click a .md file and it renders, then updates in place while your agents rewrite it on disk.

Agents leave .md files in every repo: HANDOFF, PLAN, DECISION. On a Mac, double-clicking one opened VS Code with the ### signs showing. I wanted a clean reader that feels native on the latest macOS. Preview.app for Markdown.

A reader has almost no features to hide behind. So most of the work went into making select, copy and scroll feel right.

• Updates in place, your scroll stays put
• A blue bar marks what changed since you last looked
• Copy a passage with its file path and line numbers
• Quick Look for .md files in Finder
• No account, no internet, no plugins, no AI
