MDown

Markdown, made native.

A fast, focused markdown editor for macOS. Write in raw markdown or in the rendered view — both are real editors, and you can switch freely. Open a file, write, save. Done.

Coming Soon · Mac App Store Get support ↓



Two editors, one document

The rendered preview isn't a preview — it's a fully editable writing surface. Build your whole document in either mode.

Your markdown stays yours

Untouched content is preserved byte-for-byte. MDown never silently reformats or normalizes what you didn't edit.

Cascading headings

Promote or demote a heading and its whole subtree follows. Restructure documents without bookkeeping.

Tables without tears

A visual table builder, tab-through editing, and clean markdown output on the other side.

Native and instant

Built in SwiftUI for macOS. Launches instantly, respects your Mac's conventions, light and dark mode both designed on purpose.

Six appearances

Color families from warm paper to forest green — every one intentional in both light and dark.


  • Not a note-taking system — no library, no folders, no tags
  • Not a knowledge base — no backlinks, no graph view
  • Not a cloud app — no accounts, no sync, no login
  • Not a subscription to another "second brain"

Your files, on your disk, in a format you'll still be able to read in thirty years.
