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 chapters and sentences, empty or duplicate chapters, leaked markup and filler words, and estimates where a shopper's free sample ends. The contradiction check quotes both passages when your book says two different things. Nothing is rewritten. 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. A FULL EDITOR FOR EVERY BOOK Generated does not mean final. Rewrite any chapter, add a new one in your book's voice, split or join chapters, and restore any version. Your tools sit in five sections: Write, Explore, Check, Improve and Export. Free readings show where your voice drifts and what you repeat. Paid ones are priced first. 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. CREATOR STUDIO Writing beyond books? A workspace per channel for scripts, outlines, threads and newsletters in your voice. FREE TOOLS, NO ACCOUNT Outline generator, KDP royalty calculator, audiobook length, children's word count, memoir questions, first-page analysis. No signup, no AI.
