Questions
Why not just use ChatGPT or Claude?
They can write a chapter. They can’t finish a book. AuthorOS keeps your writing style across every chapter, cites the sources behind your claims and builds the notes and bibliography, checks the whole book for contradictions, and makes the cover, listing, and EPUB. You get a finished book, not a pile of chat exports you have to source and stitch together yourself.
Is the book really mine?
Yes. You own the manuscript and every file, and the book is yours to publish under your own name. It’s written from your knowledge, in a style based on samples of your own writing. You read every chapter and can edit any line or rewrite a passage before anything is final.
What does it cost?
One flat price of $299 per book. That covers any length up to 100,000 words at the highest quality, with the cover, listing, EPUB, and 60 illustrations included. You pay once, with no subscription. Early adopters can enter the discount code at checkout.
What if it doesn’t sound like me?
AuthorOS writes from samples of your own writing, so it sounds like you from the start. If a passage still doesn’t, flag it and AuthorOS rewrites it against your sample. And before you pay, you can read your free chapters and download an EPUB and PDF of your own book, so you only pay once you can see it sounds like you.
