Two ways to a manuscript
Some people want to hand over a topic and read the result. Others arrive with a finished outline. Both work.
The controlled way
You provide the outline. book·gpt writes along your structure and keeps the whole book consistent, from the first chapter to the last.
- Your own outline as the foundation
- Chapter count and length per chapter adjustable
- Six book languages, interface in English and German
The workflow
One book, three tangible steps
Pick a step. These icons are a short tour through the product, not decoration.
Your outline remains the backbone
Start quickly from a topic or bring your own outline. Chapters, sequence and target length stay visible and editable.
- Quick start or custom structure
- Cost check before writing
Images and charts stay replaceable
Visuals are handled as individual blocks. Replace an image, regenerate it or revise its prompt without rebuilding the manuscript.
- Sources required for charts
- Alt text and history per block
One manuscript leaves in three formats
EPUB for e-readers, KDP DOCX for upload and a typeset print PDF are produced from the same content.
- 17 KDP trim sizes
- Lead magnet and large print
The costs come first
Before each run, book·gpt prices the job and shows an estimate. Writing starts only after you have seen the number. Afterwards, the actual usage appears right next to it.
Subscription tools bury this number in credit arithmetic. Here it sits on screen, in plain currency.
Visual Edition: one manuscript, fully typeset
For consultants, coaches and associations who use a book to build trust: as a talk handout, as a lead magnet on the website, or as a printed guide. Charts are built strictly from numbers stated in the text. Invented statistics have no place in a guide that carries your name.
And because many readers are past 60, the same content also ships as a large-print edition: bigger type, calm line length, verified contrast.
Lead magnet edition
Compact A4 layout for websites and talks.
Open PDF ↗Large print edition
The same content, typeset for older readers.
Open PDF ↗Both PDFs come from the same manuscript. The sample guide is in German; the pipeline writes English books the same way.
Three exports, one manuscript
For e-readers and the KDP ebook track.
Manuscript in 17 trim sizes for the paperback upload.
Typeset layout, available in large print.
Amazon KDP
Prepared for KDP compliance
Since 2023, Amazon has required that AI-generated content be disclosed at publication. book·gpt treats that as part of the product: the disclosure details ship with every book.
Final approval stays with you. You read, you edit, you decide what appears under your name. Amazon also caps new titles at ten per format and week; anyone promising books on a conveyor belt is skipping that rule.

Common questions
How long can the book be?
Up to about 90,000 words, the size of a grown non-fiction book. Shorter formats such as a 50-page guide work just as well.
Which languages does book·gpt write?
Six book languages, including English and German. The interface is available in English and German.
How long does generation take?
Usually under an hour, depending on length. While it runs, you can watch which chapter is being written.
Who owns the finished book?
You do. Sell it, give it away, or publish it on Amazon KDP. KDP requires disclosure of AI content there; we include the details you need.
Why is the allocation limited?
Every generation costs us real API budget the moment it runs. We sell only as many books as that budget covers, then open the next allocation. That is the whole trick: there is none.
