Where plans get made.
And then get done.

A native Mac notes app. You write in plain markdown, in a folder you own. Your coding agent works in the margin, waiting for your yes.

Free to write. Forever.

The markdown editor is free for everyone. The agent harness is $49 — once, not a month. It runs the coding agents you already use: Claude Code, Codex, or Cursor.

  • Your notes are plain markdown files, in a folder you own.
  • Agents read only the documents you label. Everything else is invisible.
  • Keep your notes alive by citing numbers or logic from connected databases.
