How it works

Four guided steps. You see the credit estimate before anything is made.
Describe it
Write a sentence about your book. Pick coloring, activity, picture book or novel, an audience and an art style.
Edit the plan
Bookhatch outlines every page or chapter and the characters. Reorder, rewrite or remove anything first.
Review as it's made
Pages are written and drawn two at a time, so you can check the style early. You only pay for what's made.
Download and publish

Who it's for
Built for people who want a book on the shelf
Most Bookhatch books start with one of these goals.
Test more ideas for less
Try a theme as a 12-design coloring book or a 20-puzzle activity book for a few dollars of credits, then expand the ones that sell.
A story that is theirs
Turn the bedtime story you keep telling into a printed picture book, with the child's favourite animal as the hero.
Classroom-ready packs
Make word searches on this term's vocabulary or a short chapter book pitched at your readers' level, with a printed answer key.
From premise to draft
Shape a chapter outline, get a full first draft and a typeset paperback, then revise it in your own voice before you publish.
Bookhatch vs. doing it by hand
Where the time goes in a print book
Making a KDP paperback by hand means several tools and a lot of measuring. Here is what changes.
| Task | Doing it by hand | With Bookhatch |
|---|---|---|
| Planning | An outline in a document or spreadsheet | A page-by-page or chapter outline you edit before anything is made |
| Artwork | Draw it yourself or commission an illustrator | Generated in one of 39 styles; redo any page you don't like |
| Interior layout | Set page size, margins and bleed in design software | Laid out to KDP's trim, margin and bleed rules automatically |
| Cover | Work out the spine width and build a full-wrap template | A full-wrap cover PDF sized to your final page count |
| Puzzles and answer keys | Build each puzzle and its solution by hand | Generated in code, with a numbered answer key |
| Listing | Write the description and research keywords | A drafted title, description and seven keywords to edit |
| Cost | Software, illustrator fees or many hours of your time | Credits, with the estimate shown before you start |
What stays your job: reading every page before you publish, answering KDP's AI disclosure question honestly, choosing your price and categories, and marketing the book. Bookhatch makes the files; you are the publisher.

Questions about Bookhatch
Is Bookhatch free?
Yes, to start. A free account gets 300 credits with no card to plan and write your book, and activity and puzzle books can be finished free. Line art, illustrations and covers need a paid plan or a $10 top-up. Files are the same clean, print-ready files on every plan.
What files do I get?
A print-ready interior PDF at your trim size, a full-wrap cover PDF (back, spine and front with bleed), and a listing file with your title, subtitle, description, seven keywords and print settings.
Does Amazon allow AI-generated books?
Yes. KDP accepts AI-generated content but asks you to say so when you publish a new book or republish an edited one. Bookhatch reminds you at export. Our AI disclosure guide explains the rule.
Can I sell the books I make?
Yes. You can publish and sell the books you make on Amazon KDP or anywhere else, without paying Bookhatch a royalty. You are responsible for following each store's content rules.
Will KDP accept the files?
Files follow KDP's published rules for trim size, margins, bleed and cover size. KDP still reviews every book and makes its own decision, so check your files in KDP's previewer and order a proof copy before you publish.
Which book types can I make?
Coloring books, activity and puzzle books, picture books, bedtime stories, novels, novellas and short story collections, and early chapter books. Compare all book types.
How much does one book cost?
It depends on length and type. A 12-design coloring book is about 287 credits and a 16-page picture book about 558. You see the exact estimate before anything is charged. See pricing.
Do I need design software or formatting skills?
No. Page size, margins, bleed, spine width and cover size are set from your book type and final page count. You can still change the trim size and paper before you export.
Can I edit the book before and after it is made?
Yes. You edit the plan or outline before any pages are made, and you can rewrite text or redo individual pages afterwards. Only the pages you redo use credits.
Will characters look the same on every page?
Characters are described once in the plan and a reference image is used for every illustration, which keeps them far more consistent than one-off prompts. Review each page and redo any that drift.
Which trim sizes and papers are supported?
Common KDP paperback sizes from 5 × 8 in to 8.5 × 11 in, on white or cream paper with black ink, or white paper with color ink. Each book type starts on the size buyers expect. See the trim size guide.
Can I publish a Kindle eBook too?
Bookhatch makes paperback print files. KDP's Kindle eBooks use different formats, so an eBook edition would need converting separately, for example with Amazon's free Kindle Create tool.
Do I need an ISBN?
You choose an ISBN inside KDP when you publish. KDP offers a free ISBN for paperbacks, or you can use your own. Bookhatch keeps the barcode area on the back cover clear either way. See the ISBN and low-content guide.
Is Bookhatch affiliated with Amazon?
No. Bookhatch is an independent tool. Amazon, Kindle and KDP are trademarks of Amazon.com, Inc.
About
What is Bookhatch?
Bookhatch is an AI book generator for self-publishers. You describe a book in plain words; it plans the pages or chapters, writes the text, draws the art, and formats everything to Amazon KDP's paperback rules.
It's built for people who want a book on Amazon this week, not this year: parents, teachers, hobby authors and low-content publishers who would rather spend their time on ideas and marketing than on margins and spine widths.
