Phase 1

Pick a Winner

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.

Phase 2

Write the Book

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.

Phase 3

Publish & Sell

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.

"I've finished writing my non-fiction guide using CoAuthor, and I can honestly say that, at this moment, you are the best book-writing software in the world. I've tested many other tools, including Designrr, YouBooks, Atticus, Typeset and several others. After real-world usage, CoAuthor stands out as the strongest overall solution."
