A quiet Markdown editor for Mac, with sums in your notes
Coffee is a native Mac Markdown editor. Your notes stay plain Markdown files in a folder you choose. Answers to sums appear beside the line, maths and Mermaid diagrams are drawn natively, and you review every change an AI tool makes to a note. 14 days free.
Hi, I'm Pedro. I made Coffee because I wanted one Mac app for writing in Markdown that stays out of the way, keeps notes as plain files, and answers the small sums I write anyway: a trip budget, hours times a rate, how many workdays are left.
1.4 is about finding your way around a big library: folders in the sidebar with pinned notes and a sort order per folder, replace across all your notes with a preview where you can untick any change, and version history that says what changed ("New section 'Goals', +40 words") and lets you name the versions you want to keep. Light and dark can also follow a schedule you set.
Earlier versions added maths and Mermaid diagrams drawn natively (no web view), calculations in plain words, and EPUB books from a folder of notes.
It's Mac only for now. I'd really like to hear what you'd change.
