Four Example Books, Ready for KDP

Each one shows what you get: the cover, a page from the interior and the full listing you paste into KDP. Tap a book to open it.

The example books and pen names are invented to show the output. Covers and illustrations were generated with the same image model the app uses.

What You Take to KDP

Everything the KDP setup screens ask for, prepared in one place from your own book.

Finished manuscript

Chapters written from your outline, with front matter, back matter and an automatic table of contents.

Title, subtitle and author

The subtitle is drafted to carry your main search phrase, and every field stays editable.

Book description

A blurb written from your actual chapters, ready to paste into the KDP description box.

7 backend keywords

One phrase for each of KDP's seven keyword slots, with optional keyword research to go deeper.

Category suggestions

Three to five categories that match your book's genre and audience.

Front cover

1840 x 2784 px at the 2:3 ratio KDP recommends, in 20 styles, or upload your own.

Upload-ready files

EPUB for the Kindle eBook, a print-ready PDF for paperback, and DOCX if you want to keep editing.

For a paperback, KDP needs a full wraparound cover with spine and back. The book formatter builds it from your front cover and blurb, with the spine sized to your page count and paper.

What Hurts KDP Books

Reviews and rankings reward care, and punish shortcuts.

Reviews that call out AI prose

Readers recognise generic AI text, and one-star reviews follow.

Formatting rejections

Wrong trim sizes, broken EPUBs and bad margins send files back or make paperbacks look amateur.

A listing that hides the book

Weak blurbs, empty keyword slots and wrong categories bury good books.

Retyping every KDP field

Every title, subtitle, description and category typed and retyped by hand.

From Manuscript to KDP Listing

Write, edit, format and distribute, with quality checked at every stage.

1.Write

Write it in your voice

Start from an idea or bring the draft you already have. Add a sample of your writing, shape the outline and characters, then write chapter by chapter. The AI proposes each chapter; you decide what stays.

  • Paste 6 to 10 paragraphs of your own writing and every chapter follows that style
  • Import a Word .docx of up to 200,000 words without a line of it rewritten
  • An outline, characters and chapters you can reorder, edit or rewrite
  • Choose the model for each chapter: Gemini, Claude or Grok
  • Standing instructions for the book, extra instructions for any chapter

2.Edit

Edit without losing yourself

Editing keeps your voice and leaves every decision to you. Ask for a change and see it as a diff, or run the Book Editor for an editorial letter, line edits and a proofread you review suggestion by suggestion.

  • Chapter chat shows every change as a diff you accept or reject
  • Book Editor: an editorial letter, a style sheet, line edits and a proofread
  • Every suggested replacement is accepted or rejected one by one
  • AI proofreader with several fixes to choose from for each issue
  • Edit any line yourself in the editor, whenever you like

3.Format

Format files built for KDP

Choose an interior theme, font and one of nine trim sizes, then export a print PDF and an EPUB that is validated before upload, with a cover at the KDP ratio.

  • Five interior themes and 12 embedded body fonts
  • Nine trim sizes, with front and back matter built in
  • Print PDF, EPUB and DOCX, with EPUB validation
  • A cover at the 1840 x 2784 KDP ratio, or upload your own
  • An audiobook made from the same manuscript

4.Distribute

Publish with the KDP extension

The KDP Publishing Assistant checks every field, fills the Details, Content and Pricing pages from your book, suggests a price and runs keyword research with real Amazon data from your own browser. You review each page and press Publish.
