AI Book Studio (Bookfolio)

AI Book Studio is part of Bookfolio Creator. You fill in a brief (fiction or non fiction, genre, audience, tone, point of view and length), and it proposes a title, a blurb and a chapter by chapter outline that you can rename, reorder and rewrite before anything is drafted. Chapters are then written one after another, each with a summary of what came before so names and plot stay consistent. It supports 28 genres and 12 languages.

At the end it makes a cover in the same flow and exports an EPUB, or you can open the book in the Creator editor to keep rewriting. There is no subscription. You buy credit packs and see the cost of each step before you spend, and credits for a failed step are refunded. New accounts get 8 free credits, enough to plan a short book or make a cover. Treat the output as a fast first draft, and check each store's rules on disclosing AI assisted books before you publish.
