Writing progress
See daily word counts, strongest writing hours, and recent sessions in one calm ledger.
Character arcs
Follow each major character across the book with clear lanes, turning points, and narrative transitions.

Your files stay yours
No cloud lock-in. No AI ingestion. Your novel lives in plain ASCII `.txt`, with structure and formatting stored separately in human readable format. Rest assured: your manuscript stays readable and recoverable decades from now, without depending on a proprietary formats.
Writing rituals
Keep a private ledger of the day’s work, from the mood that opens the page to the notes, weather, music, and details you choose to preserve. Add your own journal fields, keep every entry on your own machine, and write with the assurance that nothing is uploaded to the cloud.
