I already wrote my book. Can I use BookyAI without generating it with AI?

Yes. Click "Import" in your Library (or the "Import your manuscript" tile) and load your finished manuscript. Once imported, everything works on it: plagiarism and grammar checks, the chapter editor, AI covers, and KDP-ready exports (EPUB, PDF, DOCX, AZW3, HTML, Markdown) — plus audiobooks if you own BookyAI Audio.
