The Proof Object

How Experts Turn Decades of Work Into the Book That Speaks for Them. Read the first chapters and download the EPUB, PDF, and Word files. No sign-up. Every book you make comes out like this.

Your book shows its sources.

Nonfiction chapters are written with live web research. Every claim is cited or flagged, so you can check the book before you publish.

A source behind every claim

AuthorOS marks the source behind each claim: your uploaded material, the web page it drew from, or a source you add. Click any citation to see where it came from.

A claim check before you publish

AuthorOS lists every factual claim and shows which ones have a source and which do not. You add a source or cut the claim. AuthorOS does not decide a claim is true. It shows you what to check.

Notes and a bibliography

Real endnotes, numbered by chapter, with a sources list at the end. Put notes at the end of each chapter or the end of the book. On Kindle they show as pop-up notes.

Not a folder of ChatGPT chapters.

A chatbot can write a chapter. It can’t finish a book. AuthorOS does the whole job in one place.

Your writing style across every chapter

ChatGPT or Claude

Re-paste a sample each session. Drift after a few prompts.

AuthorOS

Style captured once. Applied to every chapter, automatically.

Multi-chapter consistency

ChatGPT or Claude

You track characters, timeline, and terms yourself.

AuthorOS

A style guide, plus a check that flags contradictions across the whole book.

A source behind every claim

ChatGPT or Claude

Text with no sources. You add citations yourself, if you can find them.

AuthorOS

Each claim is cited to your material, the web page it drew from, or a source you add.

Illustrations inside the book

ChatGPT or Claude

Generate images in another tool. Different style each time. Place them yourself.

Generated in the chapter, in one consistent style, and built into the EPUB. 60 included.

EPUB you can upload to KDP

ChatGPT or Claude

No EPUB export.

EPUB, PDF, DOCX, and Markdown. One click each.

What it costs

ChatGPT or Claude

A monthly subscription whether you ship or not.

AuthorOS

One price per book. No subscription.

You stay the author.

AuthorOS writes in your voice, learned from a sample of your own writing. You read every chapter, edit any line, and rewrite any passage by telling it what to change. Nothing is final until you approve it.

How it works

Four steps, one workflow. Before you pay, you can download an EPUB and PDF of your own book with your free chapters, the cover, and the listing. You see the finished book, not just text.

  1. 01

    Plan

    A brief, your ideas, and an outline. All worked out before any writing starts.

  2. 02

    Write

    Every chapter is written in your style, then improved before you read it.

  3. 03

    Prepare

    Title page, copyright, a back-cover listing, and cover art sized for Kindle.

  4. 04

    Publish

    Export a Kindle-ready EPUB, plus PDF and Word, with a step-by-step guide for publishing on Amazon.

Testimonials

From people who finished their books.

“Life always pushed writing to “someday.” AuthorOS turned that someday into today. It gave me the structure and momentum to finally write the book, even within a packed schedule. I genuinely don’t think my book would exist without it.”

Senior professional & author

“The quality was so much better that I was able to do in one day what I had been working on over a week, and even more.”

Published English Writer and Educator

“One of the best book generators for serious writers who don’t want a 10-minute book.”

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.
