Book Witch is an AI writing studio built to take a novel from a short description through to a publish-ready manuscript, holding the whole book (characters, setting, plot, style) in memory across every chapter it generates. It is operated by Fabien BOCO, a French solo developer trading as an auto-entrepreneur out of Colomiers, France; the tool was in public circulation by December 2023, when it was first featured on the directory There's An AI For That.
Writers describe a book idea, and Book Witch builds chapters and subchapters that stay consistent with earlier plot and character details rather than generating each chapter in isolation. A built-in editor supports rewriting, paraphrasing, and style adjustments; users can attach source articles or research as reference material and set custom writing guidelines the AI follows; and finished manuscripts export as EPUB or a print-ready PDF formatted to Amazon KDP's specifications.
It fits independent authors and small publishers who want a full first draft built in one pass rather than one scene at a time. Pricing runs a free plan capped at 3,000 words, a Pro plan at $19/month for unlimited words with priority support, and a $99 one-time lifetime-access deal offered through DealFuel.
