BookFoundry: AI Book Writer

You have a book in you. BookFoundry gets it out.
Type one idea and watch it become a complete book: structured chapters that flow from the first page to the last, a designed cover, and files you can upload to Amazon KDP.
No blank page. No stalled draft. A real book, start to finish.

ONE IDEA BECOMES A WHOLE BOOK
Tell BookFoundry what your book is about. It builds the full manuscript, chapter after chapter, each one picking up where the last left off, so the last chapter remembers the first.

EVERY KIND OF BOOK
Novels and fiction. Nonfiction. Memoirs, family history and life stories. Children's and picture books. Short story collections. Screenplays. Or open a blank project and build it your way. Preserve a grandparent's story. Make a bedtime book for your kid. Write the novel you have carried for years.

AS SIMPLE OR AS DEEP AS YOU LIKE
Answer four questions and start writing. Or open the full blueprint: characters with wants, wounds and arcs, a relationship map, world rules and prose controls. Continue a novel as book two and the cast, world and voice carry over.

ALREADY HAVE A DRAFT? BRING IT
Import DOCX, EPUB, PDF, TXT or Markdown and keep working on it here: edit it, analyze it, translate it, narrate it and export it like any book you started here.

READ YOUR MANUSCRIPT BEFORE YOUR READERS DO
Manuscript Analysis counts what can be counted: chapter and sentence statistics, empty or duplicate chapters, leaked markup, filler words, and an estimate of where a shopper's free sample runs out. The contradiction check reads the whole book and quotes both passages when it says two different things about the same person or fact. It never rewrites a word. Every change stays yours.

AI DETECTOR AND HUMANIZE
Check how a passage reads with the built-in detector: a verdict, a sentence-by-sentence heatmap and a plain explanation. Then rewrite it in a human voice, anchored on a fingerprint saved from your own writing.

EDIT EVERY CHAPTER, YOUR WAY
Generated does not mean final. Open any chapter in the rich-text editor, rewrite a passage, change a word across the whole book for free, reorder chapters, and snapshot a version you can restore.

YOUR COVER, DESIGNED IN-APP
Pick from generated covers, upload your own image, or compose one in Cover Studio with layouts, text effects, fonts and image layers. Then set the interior: 23 typeset themes, drop caps, scene breaks and spacing, previewed in real device frames.

TURN YOUR BOOK INTO AN AUDIOBOOK
Give your finished book a voice, then download it as M4B, M4A or MP3.

REACH READERS IN OTHER LANGUAGES
Translate your book and get a natural, native-sounding result. Not literal. Not stiff. Writing that reads like it was written in that language.

READY FOR THE STORE
Export EPUB, DOCX, print PDF and your cover at no extra cost. Get a store listing written for you: description, keywords and categories checked against the real Amazon KDP tree. Estimate page count and royalties first. Or publish it as a public page and share the link.
