Use tool ↗About First Book AI
First Book AI is a web app for professionals who want to publish a nonfiction book without hiring a ghostwriter. You describe your expertise and goals, the app drafts an eight-chapter outline, then generates chapter text in a voice you can edit before export. Outline generation is free; finished books are paid for with credits that do not expire. The team says it is based in Copenhagen, though no formal company name is listed on the site. Output can be downloaded as Word, EPUB, Markdown, or PDF, so writers can keep editing in their own tools after export.

Pros & cons of First Book AI
First Book AI is useful for someone with real expertise who wants a structured first draft fast rather than a blank page. The free outline is a low-risk way to see if the structure fits before paying, but the writing still needs a human edit pass to sound less templated.
Pros
- Free outline before any payment is required
- Credits never expire, so there is no subscription to forget about
- Exports to Word, EPUB, Markdown, and PDF for further editing
Cons
- Only handles nonfiction, not fiction
- No registered company name on the site, only a founder and Danish governing law
- Chapter text still needs a real editing pass before publication
Best for
- Consultants and coaches turning talks or frameworks into a book
- Founders who want a lead-generating book without hiring a ghostwriter
- Writers who work better editing a draft than starting from nothing
Not for
- Fiction writers
- Anyone who needs a finished manuscript with no further editing
Watch out: The 30-day refund only holds while you have generated one book or less, so test the voice on the free outline and a single credit before buying a pack.
