Coffee

Coffee is a native Markdown editor for the Mac. Your notes stay plain Markdown files in a folder you own, so nothing is locked in.

Write a sum in plain words and the answer appears beside the line: trip budgets, hours times a rate, currencies, time zones, days until a date. Maths and Mermaid diagrams are drawn natively, without a web view. You can import Word files, export to PDF, Word and EPUB, and review every change an AI tool like Claude or Cursor makes to a note before keeping it.

Made by one person in Portugal. 14 days free, then from €3 a month.
