Review what the AI changed

When Claude, Cursor or anything else edits a note outside Coffee, such as a Git pull or a synced folder, each change is shown and can be kept or undone one at a time.

Coffee is a Markdown editor for the Mac, on macOS 15 or later. It looks at the file rather than the tool, so it doesn't matter which AI app made the edit.

See every change

You don't have to trust a whole rewrite or read a diff in another tool. Coffee remembers each note as you last read it. If the text on disk is different, a small bar at the top says how many changes there are.

Press Review and every change is a card, under the heading it falls in, with the old text and the new text. Each card has Keep and Undo, and there's Keep all and Undo all at the bottom. Undo is an ordinary edit, so ⌘Z brings it back. Every note also has version history, with restores you can undo.

What the review won't do

It compares whole lines, so a changed paragraph shows as old paragraph and new paragraph, with no highlight on the changed word.
It needs a first read. Changes made before Coffee first opened a note don't show up as changes.
It can't tell you who made a change, only that the file changed.
It skips private notes.
It isn't version control. If you need a record to share, use Git.

Connect your AI apps

An MCP server lets Claude and other apps read and write your notes. It is off until you turn it on, and switches choose whether AI apps can read notes and edit them.

Send changes to Git without using Git

Propose change sends one note to a new branch and opens a pull request, leaving your working tree alone. Handy for teams who keep documents in Git, including people on them who don't use Git.

Questions

Which AI tools work with Coffee?

Any tool that edits the .md files, such as Claude or Cursor, and any app that supports MCP can connect to it.

Can AI apps read my Private notes?

No. AI apps never get a Private note's text or images. A switch in Settings decides whether they can see its title in the list of notes, and it hides titles until you change it.

Does Coffee send my notes to an AI service?

Search and Ask run on your Mac. A connected AI app can read the notes you allow it to, under that app's own terms.

What does it cost?

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