marcdown
the most beautiful place for your markdown. whoever wrote it.
you write. your agents write. marc looks after every word, and makes it magnifique.
- native Mac
- plain files
- pay once
- no AI inside
markdown as you write it.
marcdown shows your notes the way they will read, and shows the syntax only where your cursor is. Everything below is in the free app.
live preview
Tables, callouts, footnotes, code with highlighting, math and Mermaid diagrams, right in the editor.
your folders, your files
Open any folder. Notes stay plain .md files, and marcdown never rewrites a line you did not touch.
fast everywhere
Quick open, folder search, tags, an outline, and a command palette that understands plain phrases like "make a table".
capture
A global hotkey saves a thought to your inbox from any app.
a good Mac citizen
Quick Look, the marc command, EDITOR='marc --wait', three ink-only themes, light and dark.
see what changed
When a note changes on disk (an agent, git, sync), marcdown updates it and shows you what changed.
a shared desk for you and your agents.
Your agents already write in your markdown, and your markdown already shapes your agents. marcdown sits where the two meet.
agents can reach your notes
marc mcp lets Claude, Cursor and other agents search your notes, read a section, see what you are looking at (only if you allow it) and open a note for you.
agent files, made readable
CLAUDE.md, AGENTS.md, skills and rules get their own calm view, so the text your agents read stays tidy.
no AI inside
marcdown never writes for you and never sends your notes anywhere. Bring your own agent; marcdown gives it context and gives you the final say.
claude mcp add marcdown -- marc mcp
encore. the flourish.
The free app does the work. encore adds a few things for people who live in their notes. One payment, from €19.
review changes
Accept or undo what others changed, section by section. Pencil marks in the margin, and a list of every note that changed since you last looked.
beautiful export
PDF and HTML with the theme's typography.
writing room
Focus mode dims everything but the paragraph you are writing. Typewriter mode keeps your line in the middle.
