## What Bookwiz is

A browser writing room with an AI assistant that has read your whole manuscript and your notes. You describe the book in a sentence, accept the chapter outline it drafts, then write chapter by chapter with Claude, GPT or Gemini, switching models per prompt; you can also import a draft. When the book is done, its Publish Kit exports a reflowable EPUB, a print-ready PDF, a DOCX and a full-wrap paperback cover, makes an AI cover from a mood you describe, and on paid plans writes an Amazon listing pack (title options, 7 keywords, BISAC categories, a description and a price).

## Where Bookwiz shines
- An assistant that has read the whole manuscript and your notes, so you don't re-paste chapters into a new chat.
- KDP-ready export on every plan, Free included: a reflowable EPUB, a print PDF, a DOCX and a full-wrap paperback cover.
- Claude, GPT and Gemini in the same book, switched per prompt (Claude Sonnet, Claude Opus and Gemini Pro on paid plans).
- A $79 one-time pass for a book you already wrote: the listing pack, a launch kit and a zip of the KDP files, with no subscription.
- Your books stay yours: its terms leave you full ownership (AI suggestions become yours when you accept and use them), cancelling or downgrading never deletes a book, which still exports as an EPUB, print PDF and DOCX on the free plan, and a 30-day money-back guarantee covers the first subscription and each pass.
