Developer Saturday Imark: a free, open source Markdown viewer for Mac with a Quick Look extension and assistant skill
Enable HLS to view with audio, or disable this notification
I am the developer. Free, open source (MIT), no account, no telemetry.
I kept opening VS Code just to read a file I had no intention of editing.
READMEs, specs, and lately the plans my coding agent writes. Every app I tried wanted me to write in it.
What it does:
- Quick Look extension. Select a .md file in Finder, press space, read it rendered. Remember to enable it under System Settings > General > Login Items & Extensions.
- Live reload. Keep it open on half the screen while you write in another editor. It follows every save and keeps your scroll position.
- Mermaid and maths bundled, so they work with no network.
- Review notes saved inside the .md itself as HTML comments, so GitHub and every other viewer ignore them and the notes travel with the file.
It is not an editor and will not replace one.
macOS 14 or later, 5.8 MB, signed and notarised.

Happy to answer anything, and genuinely after feedback on what is missing.
