AI co-writing tool that turns a professional's expertise into a nonfiction book outline and chapters.
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.
Outline generation is free; a single book costs one credit at $29, with bulk credit packs (5 for $69, 20 for $199) lowering the per-book price.
Use tool ↗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.
Watch out: The site names only a city (Copenhagen), not a registered company, so there is little to check before paying for credits.
