Write overview
Write is where the book actually gets written. The editor stays out of your way: clean serif text on a quiet background, autosave running so you can stop thinking about saving, and a sepia mode for long evening sessions.
Every change is versioned at the chapter level, so undo extends across sessions. Drop in a paragraph today, rewrite it tomorrow, and yesterday's version is still recoverable from the chapter history.
On Loom and Tapestry, an AI assistant sits beside the page with full context of your Plan studio. Ask it for a rewrite, a continuation, or a sanity check on a scene, and it answers using the characters, beats, and research you already built. On Thread and Spool the page is yours alone, no model in the loop.
