Notes that cost a coffee.

A quiet Markdown editor for the Mac. Your notes stay plain files in a folder you own, and everything else steps out of the way.

Trip to Lisbon

Four days in May. Stay near the river, walk everywhere

Don't take our word for it. Type.

Write Markdown or just write. See the finished page, the code, or both side by side and type in either one. Press ⌥⌘/ in the app.

This is the real Markdown engine from Coffee. Type on the left, and watch the right.

• Headings with #
• Italic, bold, and code
• A link

Switch views with the buttons above.

Write the question. The answer is already there.

Sums, currencies, time zones and more, in plain words, in any note. The answer sits beside the line and never goes into your file. Go on, change a number. In the app, hold ⌥ and drag one to try another value, or select a column of numbers to see its total.

• Currencies and crypto $30 in EUR, 1 BTC in USD
• Time zones Tokyo time, 2:30 pm HKT in Berlin
• Dates 3 days ago, workdays until 24 Dec
• Time and rates 3h 5m + 45 min, €40/hour * 7.5 hours
• Units 5 km in miles, 100 C in F, 1 GB in MB
• Percentages 20% of 50, 20 is what % of 200
• Variables and totals price = $8 times 5, sum, average
• Maths sqrt 16, 255 in hex, 7 mod 3

What's saved, and what you see

Coffee never writes an answer into your note. The file keeps only what you typed, so other editors, Git, and the people you share it with see just that. PDF, Word and EPUB exports print each answer as it stood when you exported, so 3 days ago stays that day's date.

In the .md file

• Lisbon trip

• Hotel: €95 * 3
• Train: €42 + €42
• Dinners: €28 * 4
• total
• Booked: 3 days ago

Your Word documents, as notes.

Drop a .docx on Coffee and it becomes a note, with its headings, lists, tables, links and pictures still in place. It's plain Markdown from then on, and the original stays exactly as it was. When someone needs a Word file back, export one.

See what the AI changed

When Claude, Cursor or anything else edits a note's file, Coffee lays out every change. Keep or undo them one at a time.

Q3 report

Revenue grew 12%, led by the new plans.

• Two more markets
• Support answers within a day

Propose a change, without learning Git

Your docs live in a repository, and half your team can't touch them. Now they can: write it, describe it, press Propose. Coffee sends only that note to a new branch and opens the pull request. Nothing else on your Mac changes.

Find anything as you type

Press ⌘K and every note answers on the first letter, accents included. It takes about 14 milliseconds across 5,000 notes. Try it: type "sao" or "tram".

What still needs doing before Lisbon?

Two things: find a place near Alfama, and ask Ana about the tram.

PDFs that look designed

Letterhead, title pages and page numbers, with no layout app. Press ⌘E. Export Word, EPUB, HTML, Markdown, and plain text too.

And everything you'd want from a writing app.

Comments stay out of the file. Your Markdown stays clean.

Version history

Drag it. Each version says what changed, the ones you name are kept, and restoring can be undone.

Private notes

Touch ID, encrypted on disk, hidden from search and AI.

Keyboard sounds

Dry recordings of Cherry MX Red, Brown, and Blue. Press these keys. Off by default in the app.

Clipboard history

What you copy, searchable and encrypted on this Mac. Password managers' items are never kept.

Notes

Templates

A template is just a .md file in a folder, with the date filled in. ⌘T opens today's note.

Math, drawn natively

Write TeX between $$ lines. The formula appears under it, and in your PDFs, Word files, and books.

Diagrams from text

Mermaid flowcharts, pie charts, and sequence diagrams, drawn as you type. No web view, nothing fetched.

A book from your notes

A folder or a tag becomes one EPUB, a chapter per note, ready for Apple Books.

Connect AI apps

Let Claude and others read and write your notes over MCP. Off until you turn it on.

The small things, done right.

• Search that ignores accents Type "sao" and São Paulo turns up. Accents never stand between you and a note.
• Back where you left off Every note reopens at the line you were on.
• Files named after their titles Change the first heading and the file follows, links to it included. No IDs, no "Untitled 14".
• Nothing is lost Every note keeps its past. Restore any version, and undo the restore.
• Never merged behind your back If a note changes in two places at once, Coffee keeps both versions and lets you choose.
• Your file stays yours Comments, answers to sums and reviews of AI edits live beside the note, never inside the .md.
