- Think in trees, not lists
- Every line can hold more lines, as deep as you need
- Where a thought sits is part of what it means
- Zoom into any branch and work there as if it were the whole outline
- One tree for your topics — everything else stays flat and simple
- Nothing moves unless you move it
- No auto-sorting, no “recent” shuffles, no smart grouping
- No counts, no badges, no streaks
- Search finds anything; filing is how you remember it
- Yours, on your Mac
- The whole outline lives in one file on your machine, and opens without a network
- Plain Markdown in the file, styled text on the screen
- Sync between your Macs through a relay that cannot read a word of it
- Every machine keeps the whole history
- Export everything as plain text, any time
- A code block keeps its lines exactly as you wrote them
- let pairs = items .filter(isValid) .map(transform)
- Made for deep work
- Keyboard first — ⌘/ shows every shortcut
- Light and dark, following your Mac; nothing to configure
- Nothing is said by colour alone
- Click a bullet to fold it; click a line to write in it
- Nothing here is saved — the outline on this page is yours only until you leave it
