What is it?
MarkEdit is a free, open-source Markdown editor for macOS. It works like TextEdit but is dedicated to Markdown, aiming for a small installer (about 4 MB) that stays responsive on very large files, including files with a million lines.
MarkEdit follows the GFM specification without proprietary syntax. Complex editing features such as multi-caret editing and code folding are built on CodeMirror 6, while UI controls like word lookup, inline predictions and Writing Tools stay native to macOS.
Customization relies on CSS, JavaScript and CodeMirror extensions, and an built-in extension manager offers curated official extensions for Markdown preview, syntax hiding, themes, AI writing and visual table editing. The app supports Shortcuts and AppleScript and does not collect user data.
