Coauthor.ai Full Tutorial - How to Write a Book in a Day with AI

About this video

Sean Dollwet gives a start-to-finish tutorial on Coauthor.ai, a book-writing tool he says he partnered on with a developer who previously built and sold software to NASA, combining that developer’s software skills with Dollwet’s book-publishing knowledge. Using a decluttering book as the example, he walks through: research (title, pen/brand name, genre, topic, a unique ‘stance’ — e.g. decluttering in under 10 minutes a day — and what makes the book stand out, plus tone and audience); a market-analysis step that pulls in relevant bestsellers to learn from, with irrelevant or poorly reviewed titles removed and an explicit disclaimer that it does not copy them; AI title generation (10 options) with an in-tool chatbot for feedback; a resources section for uploading files, links or text as context, similar to ChatGPT Projects; a savable author persona (background, style, writing sample) so a series keeps one voice; a ‘proposed book’ step showing the unique selling point and how it differs from competitors such as Dana K. White and Marie Kondo; details (he picks 20,000-25,000 words, 10 chapters, problem-solution structure from options ranging 10,000-40,000 words); author biography; and a detailed outline. He stresses variable chapter/section lengths and subsection counts to avoid repetitive AI books. For writing he recommends generating one section at a time, editing it, then continuing, because the tool builds on the previous section. He demos inline editing tools including elaborate, add-source and strengthen-with-data (which inserted, as an example, a claim that the US self-storage industry generated an estimated $39.5 billion in 2018), plus diagram/image generation, then an auto-generated Amazon-style description (headline, relate, bullets, objections, call to action), a cover generator he admits is still imperfect with AI errors, and export as PDF or DOCX. He closes with a beta offer of 25% off for life for the first 1,000 sign-ups via his link, noting fewer spots remain after an earlier release in his Road to Hero community.

Key takeaways

• Give the AI extensive context before writing — stance, differentiator, resources, author persona and biography — to avoid generic, repetitive output
• Study relevant bestsellers in the analysis step, removing irrelevant or poorly reviewed titles; the tool is presented as learning from, not copying, them
• Use variable word counts and varying numbers of sections/subsections per chapter so the book’s tempo does not feel uniformly AI-generated
• Generate and edit one section at a time rather than the whole book at once, so errors are caught early and later sections build on corrected text
• Use inline tools like add-source and strengthen-with-data to back claims with sources/studies, and treat AI cover output as a draft to hand to a designer
