A Markdown editor for the Mac

Coffee is a native Mac app for writing Markdown, for macOS 15 or later on Apple silicon or Intel. Your notes stay ordinary .md files in a folder you choose, so any other editor can open them and leaving is free.

It's free for 14 days, with no card or account. After that it's €3 a month, €29 a year, or €79 once with two years of updates.

Three ways to see a note

Work in the finished page, in the code, or split, where you can type on either side and both update.

Plain files, in your folder

There is no database and no proprietary format. Pick iCloud Drive, Documents or any folder. One button in Settings makes Coffee the default app for Markdown and text files, and each file opened from Finder gets its own window.

What it does as you write

Search with ⌘K. In our tests it took about 14 milliseconds across 5,000 notes.
Calculations written in plain words, with the answer beside the line.
Paste spreadsheet cells as a table, and keep a web page's headings, lists and links.
Move whole sections by dragging a heading in the outline.
Check document finds broken links, missing images and skipped headings.
Draw $$ maths blocks, Mermaid flowcharts, pie charts and sequence diagrams, callouts and footnotes, in the note and in exports.
Export designed PDFs, plus Word, EPUB, HTML, Markdown and plain text. A folder or a tag can become one EPUB book.

Who it suits

People who write in Markdown and want a fast, focused Mac app, including anyone editing with AI tools who wants to review what changed.

What it doesn't do

It runs only on the Mac. There's no Windows, iPhone, iPad, Android or web version.
It has no sync of its own. Keep the folder in iCloud Drive or another synced folder, and that service does the work.
Two people can't type in one note at once. A change from someone else reaches you through Git or a synced folder.
It isn't a database or project-management workspace.
Inline $…$ maths is shown in italic but isn't drawn, and Mermaid kinds other than flowcharts, pie charts and sequence diagrams stay as code.

How it compares

Questions

Does Coffee use plain Markdown files?

Yes. Notes are ordinary .md files in a folder you choose, and any other editor can open them.

How much does Coffee cost?

14 days free, with no card or account. Then €3 a month, €29 a year, or €79 once with two years of updates.

What do I need to run Coffee?

A Mac with macOS 15 or later, on Apple silicon or Intel.

Does it work offline?

Yes. Everything you write works offline. Proposing a change to Git needs a connection, and currency sums use the last saved rates until Coffee can fetch new ones. Coffee checks a subscription when it can and keeps working for weeks without a connection.

Can I keep my notes in iCloud Drive?

Yes. Your library is a folder you choose, so it can be in iCloud Drive, Documents or anywhere else. Coffee itself has no sync service.
