Not everyone who
writes a book wants to sell it.

BookFoundry is an AI book generator that turns an idea, a topic, or your own content into a complete, formatted, publish-ready book with a cover, in 18 languages. It plans the outline, writes the chapters, designs the cover, and exports DOCX, EPUB, and print-ready PDF, all in one flow. Free to start, and you pay only when you create a book.

• Give it your starting point. An idea, a topic, notes, voice transcripts, or an existing file.
• Generate the book. The engine plans the structure, writes every chapter with one consistent voice, and designs a cover.
• Download or publish. Export DOCX, EPUB, and print-ready PDF, ready to upload to Amazon KDP or read anywhere.

Upload a document or book as EPUB, PDF, DOCX, or Markdown, or pick one you made with BookFoundry. We translate it into 18 languages, then a native-voice pass rewrites every chapter so it reads like a local author wrote it, not machine-translated. Your structure and formatting stay intact, and you export retail-ready DOCX, EPUB, and PDF in each language. Free to try, no credit card.

• Upload your document or book. Bring in a document or book as EPUB, PDF, DOCX, or Markdown, paste text, or pick one you made with BookFoundry.
• Choose your languages. Select one or more target languages and the dialect that fits your readers.
• Translate and export. The engine translates, runs the native-voice pass, and gives you retail-ready files in each language.

• Answer five questions. Tell us who you are writing for, your goal, your experience, your time, and what pulls you.

Paste your opening page and see what can be proven about it by counting: sentence lengths and how much they vary, how much of the page is dialogue, the filler words, and the sentences that all start the same way. Free, no account, no credits.

• Paste your opening page. Up to 800 words, which is about three manuscript pages. Nothing is stored.
• Read the counts. Sentence lengths and their variation, dialogue share, filler words, repeated openings, and anything countable that looks worth a second look.
• Take it to the whole book. The full Manuscript Analysis reads every chapter, and the layer that costs nothing there is still free.

Manuscript Analysis reads a finished draft and tells you what can be proven about it. The free layer is arithmetic over your own words: the statistics of the book, the things that would embarrass it on a store page, an estimate of where a shopper's free sample ends, and candidates where two numbers or two spellings of a name disagree. One paid reading goes further and looks for exactly two things. Nothing here rewrites a word of your book.

• Bring your draft in. Import a manuscript into Writer's Workshop, or open a book you wrote here. Analysis reads what is already there.
• Read the free layer. Statistics, publish readiness, the estimated sample cutoff, and the number and name candidates. No credits and no waiting on a model.
• Buy one reading, if you want it. The paid reading costs credits, shows its price before you agree to it, and reports what it refused alongside what it found.
