Write the nonfiction book you keep putting off

Describe your book in a sentence. Koobe plans the chapters, drafts them in order and formats the result, and you stay the author who edits every line.

The writing isn't the only hard part

The blank page wins most days

You know your subject. Turning it into a chapter plan that flows is where the weeks of false starts go.

Formatting eats your weekends

Page breaks, gutters, EPUB checks. The book is written, but the files still aren't ready to upload.

The cover is a project of its own

Briefing a designer or wrestling with templates, just to get a cover you can put on a store page.

How Koobe helps

Built for authors

An outline in seconds, then chapters in order

Rename, reorder, add or remove chapters before any writing starts. Each chapter knows what came before, so examples don't repeat.

You stay the author

Edit any line in the preview, or ask the assistant in plain words, like “make chapter 3 shorter.” Version history keeps earlier drafts you can restore.

Files the stores accept

Export EPUB 3 for Kindle, Apple Books, Kobo and Google Play Books, plus a print interior PDF for KDP and IngramSpark paperbacks.

Where you’ll use it

One book, many jobs

Amazon KDP

Upload the EPUB for Kindle and the print interior for a paperback. The cover image is sized for your store listing.

Apple Books, Kobo and Google Play

The same EPUB 3 file works across the other major ebook stores, so one book can reach readers wherever they shop.

Your own website

Sell the digital PDF as a direct download. The cover is built in, so it looks finished on any screen.

“I’m not a writer. I described a 30-day guide for new managers and it came back with chapters that made sense. Had to fix two examples that didn’t fit how we work here, and I changed the title. Files were ready for KDP, which is what I actually needed. First book I’ve finished.”

Questions from authors

See all questions or compare plans.

Can Koobe write a novel?

Koobe is built for nonfiction-style books: guides, how-tos, practical memoirs and the like. It plans chapters around ideas and can add key takeaways and exercises, so it isn't the right tool for drafting a story. If you've already written a manuscript, you can import it to design and export it without AI writing.

Who owns the book?

You do. You own what you put into Koobe and, as far as the law allows, what it generates for you. Koobe claims no ownership and doesn't use your content to train AI models.

Are the files ready for Amazon KDP?

Koobe exports an EPUB 3 file, which KDP accepts for Kindle, and a print interior PDF for paperbacks with chapters opening on right-hand pages and mirrored gutters. You upload them to KDP yourself, since Koobe doesn't publish to stores. KDP requires you to disclose AI-generated content when you publish.

Can I start from my own notes or draft?

Yes. Upload notes, an outline or a draft as PDF, DOCX, Markdown or TXT. Koobe reads roughly the first 10,000 words and builds the book in the direction of your material.
