Write the book your readers are already asking for.
Ebook Product OS listens to real conversations on your topic, groups them into the problems people actually have, researches the answers and writes a complete, evidence-backed ebook. You get the EPUB, a premium PDF, a print-ready interior, the full back cover, a workbook and a complete Amazon KDP listing kit, all in one place.
Real books, built from real reader problems.
Five niches, five very different readers. Every one researched, written, reviewed and packaged by the system, each with its own workbook.
Fast books are easy. Books people finish and recommend are not.
From a topic to a finished, listed book in three steps.
Enter a topic
Ebook Product OS scans real discussions on it and groups what people are asking into clear problem clusters. You choose the angle.
It researches and writes
Each problem becomes a chapter, answered with researched evidence in a human voice. A review panel checks that every chapter hits its goal.
Download and publish
Get the EPUB, premium PDF, print-ready interior, back cover, workbook and KDP listing kit. Upload to Amazon, set your price, publish.
Everything in one place, end to end.
No cover designer, no formatter, no copywriter for your listing. One run gives you every file Amazon KDP asks for.
Ebook file
A clean EPUB ready to upload straight to Kindle Direct Publishing.
Premium PDF
A polished, designed PDF edition you can sell direct or give away as a lead magnet.
Print-ready interior
A formatted interior for paperback, so the same book can go to print as well as Kindle.
Full back cover
Back cover built to Amazon's requirements, with copy that sells the book.
Workbook with every book
Exercises and reflection prompts that turn reading into doing, and give readers a reason to keep the book.
Full Amazon KDP listing kit
Everything you need to fill in your listing, so the book goes live without starting from a blank form.
Checked line by line, so your name is safe on the cover.
Every chapter goes through an independent review before it reaches you. Anything that sounds machine-written, states a claim more firmly than its source supports, or passes off a made-up example as fact is flagged and fixed.

Questions, answered
What exactly do I get for each book?
An EPUB, a premium PDF, a print-ready interior, a full back cover, a workbook and a full Amazon KDP listing kit. Everything in one place, end to end.
Where do the book ideas come from?
From real discussions on the topic you enter. Ebook Product OS groups what people are asking into problem clusters, and those become your chapters.
What is the difference between the plans?
Only the number of books. Both include the full package for every book.
Will it sound like AI?
Every chapter passes a review step that flags machine-sounding phrasing, overstated claims and invented examples presented as fact, and fixes them.
Can I publish in paperback too?
Yes. Every book comes with a print-ready interior and full back cover alongside the EPUB.
Is publishing AI-assisted books allowed on Amazon?
Amazon KDP allows AI-assisted content that meets its quality guidelines, with disclosure where Amazon requires it. Check KDP's current policy before publishing.
Do I need writing or design skills?
No. You choose the topic and angle; the system handles research, writing, review, the workbook, formatting and the cover.
Your readers have already written the outline. Ebook Product OS writes the book.
