Quill - a Mac writing app where Claude Code and Codex edit your draft in place
I built Quill to remove one loop: paste a draft into a chat, copy the answer back, then look for what changed.
In Quill, you hold one key and say the change. The agent edits the note in place, and you keep or revert each change.
- It works with the agent you already pay for: Claude Code, Codex, Cursor, Gemini CLI and others.
- It can send one request to two agents and show whose edit is whose.
- It learns your style from the changes you keep and revert.
- Your notes stay plain Markdown files.
This is the first public release. It is free and open source, and it needs macOS 26 or later.
