BookFoundry is an AI book-creation platform that takes you from a single idea or raw content to a finished, publish-ready book. It writes full-length manuscripts with real chapter-to-chapter continuity, designs your cover, validates Amazon KDP categories, and exports clean EPUB, PDF, and DOCX files. It supports fiction, non-fiction, memoir, children's books, and screenplays across 18 languages, with a built-in AI detector, humanizer, book formatter, and translation. Start free.
