Create non-fiction books designed to sell, without writing experience, ghostwriters, or months of work. Powered by the publishing framework responsible for millions in royalties. See it in action below.
Non-fiction only
The Workflow
Coauthor pulls real competitor data straight from Amazon and analyzes what’s actually selling, so the book you write is built on a topic that has real buyer demand. No more guessing. No more weeks of manual research.
Generate a full 50,000-word non-fiction book in under an hour, with optimized titles, structured outlines, and chapter-by-chapter writing that reads like a real author wrote it. Picking the wrong setup is the #1 reason most AI books fail, and Coauthor is built specifically to make sure that doesn’t happen.
AI editors clean up the writing, the cover generator handles design, and the description writer optimizes your listing for conversions. Everything you need to take your book from idea to live on Amazon, all in one place.
Built by a Publisher
I’ve generated over $5M in royalties from my books. After 6+ years of full-time publishing, I packaged everything I’ve learned about what makes a book sell into one piece of software.
Coauthor is built on the exact publishing framework responsible for generating millions in royalties, and it’s now trusted by 2,000+ publishers to help them write books designed to sell on Amazon KDP, Apple Books, IngramSpark, Draft2Digital, and more.

New Publisher
“So much better than asking a freelancer to generate the book. Much faster and of course much cheaper than using a writer. Plus amazingly I was not aware that Coauthor would generate a book cover for me too. And it did a great job on the first try.”
