What is Coluracetam?

Finder shows Markdown files as a gray wall of asterisks and pipes. Coluracetam fixes that at every level of the system: press space and Quick Look renders the document in full color — headings weighted, code highlighted, tables ruled — and Finder thumbnails render the same way. One rendering path drives everything, so the preview never disagrees with the app.

Open the file properly and you get a clean, GitHub-styled reader with zoom, find, and export — plus a live split editor with the source below and the preview above, updating as you type.

Requires macOS 26 (Tahoe) or later. Free and open source (MIT) on GitHub; also available on the Mac App Store.
