AIWriteBook review: AI book writer with editor, formatter, covers and audiobooks. Free plan, paid plans from $12/mo billed yearly. Features and verdict.
Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
AIWriteBook is a browser-based AI writing studio built for authors who want to produce finished books. It handles the stages that usually need separate tools: planning characters and outlines, drafting chapters, editing, formatting for print and ebook, designing covers and creating audiobooks.
The product is positioned around quality and voice. Authors can set up a writing style so the AI follows their tone, and they decide how much of the writing the AI does. Reviews on AppSumo, Trustpilot and Capterra describe it as more than a text generator because it covers the whole workflow.
The site reports more than 30,000 authors, a 4.7 Trustpilot rating from 589 reviews, and support for writing in 38 languages. Users can start from a blank idea or import an existing .docx draft.
A book starts with an idea or an imported Word draft. Imported manuscripts are parsed into chapters without changing the text. From there, users build characters, an outline in the Story Bible and a writing style, then generate chapters one at a time.
Chapters can be revised through the writing editor, and weaker sections can be regenerated without redoing the whole book. Large changes are handled with an Edit All with AI option on the outline page, after which chapters are regenerated individually.
When the text is ready, the Metadata step adds a cover, the Format step builds the print and ebook files, and the Publish step offers downloads. Audio is created separately in the Audiobook Studio.
The Book Editor reads every chapter before suggesting changes. It scores the book on 30 criteria for its genre, writes an editorial letter and runs line edits that also proofread. Authors accept or reject each change, and accepted edits go straight into the manuscript.
The formatter produces a PDF/X-1a print interior, a wrap cover with spine width calculated from page count, an EPUB and a DOCX. It offers 17 trim sizes and 12 typefaces, and a preflight check names issues a store would reject. Regenerating files is free once formatting is unlocked for a book.
Other tools include a cover maker, an Audiobook Studio, book translation, visual books for illustrated stories, series support, an author public page, and a KDP Chrome extension with keyword and category research.
