When your thoughts have thoughts.

Click a bullet to unfold a branch.

• Think in trees, not lists
  • Follow an idea from its first line to its deepest branch without losing its shape.
    • Every line can hold more lines
      • As deep as you need
  • Zoom into any branch and let it become the whole view
  • Where a thought sits is part of what it means
  • Keep every topic in one outline
• Nothing moves unless you move it
  • Your outline stays where you put it
    • No auto-sorting, no “recent” shuffles, no smart grouping
    • No counts, no badges, no streaks
  • File by meaning, not retrieval
    • Search finds anything when you need it
• Yours, on your devices
  • Works without a network
  • Your whole outline is one local file
    • Plain Markdown in the file, styled text on the screen
    • Export everything as plain text, any time
  • Sync through a server that cannot read your writing
    • Not a word leaves your device unencrypted
    • Every device keeps its own complete history
  • Code stays exactly as you wrote it
    • let pairs = items .filter(isValid) .map(transform)
• Made for deep work
  • Keyboard first
    • ⌘/ shows every shortcut
  • Native on each platform
    • Light and dark follow the system
  • The interface leaves you alone
    • No feed to check, no system to maintain
