I Built an AI Tool That Writes an Entire Book in an Hour

About this video

Dollwet unveils Co-author.ai, an AI book-writing tool he says he guided (he did no coding) over a year and a half with developers he says previously built and sold AI software to NASA. He claims it is trained on his methodology from 10 years of publishing, around 500 books and over $2.2 million in royalties — presented as his credentials, not verified results for users. He contrasts a ghostwriter at $1,000-$2,000 and about a month per book with a Co-author first draft in as little as an hour for around $50 per book depending on plan, stressing it is an assistant to edit, not a spam tool. In a live decluttering-book demo he walks the step-by-step flow: topic/stance/differentiator and audience, market analysis modeling (not copying) relevant well-reviewed bestsellers, title generation, added resources, author persona/bio, proposed book/USP and differentiation, length (he picks 20,000-25,000 words, 10 chapters) and structure, then a chapter-by-chapter outline with varied section word counts. He recommends generating and editing one section at a time, shows the inline editor (expand, grammar, add quotes/sources/data, generate diagrams/images), then auto-generated description in a five-part selling structure, a cover step he admits is still imperfect with AI text errors, and export to PDF/DOCX. The tool is in beta, offered with a 25% lifetime discount for the first 1,000 people, fewer after his coaching community was offered it.

Key takeaways

• Position AI as co-author, not replacement: generate a fast first draft, then edit section-by-section and add a personal stance/differentiator to avoid generic output.
• Feed the AI context before writing: market analysis of relevant well-reviewed bestsellers, resources, author persona and a clear unique selling point drive the outline.
• Vary chapter/section lengths and word counts to avoid the repetitive tempo typical of AI books; approve chapters, then sections, then subsections before writing.
• Use inline tools to strengthen non-fiction with stories, studies, quotes and sources/data, and to expand or add calls to action, rather than publishing unsupported assertions.
• Budget comparison he makes: ghostwriting $1,000-$2,000 and ~a month vs. ~$50/book and a draft in an hour with the tool — his claimed pricing/time, and the cover generator still needs a human designer fix.
