AI book writer for planning, drafting, revising, and exporting complete books.

Emberspun is a browser-based AI book writer and eBook generator for turning an idea into a complete, editable book. Define the reader, direction, outline, references, and publishing goal, then let the agent draft chapters and create a cover while you review and revise the result in the same workspace. Use shared book context and Story Bible tracking to keep long projects focused, and export PDF, EPUB, or DOCX files for sharing, selling, or further editing. Emberspun supports practical guides, handbooks, cookbooks, workbooks, children's books, fiction, memoirs, lead magnets, and other digital products. Review the final files and follow the requirements of your chosen publishing or sales platform before release.
