Write the whole book.
Outline it, draft it with AI, edit it, wrap a cover on it, and walk out with a print-ready interior PDF, a validated EPUB 3, a DOCX, and an audiobook script. Nothing leaves your device unless you ask it to.
Bring in a finished manuscript as .docx, .epub, .md, .html or .txt — Booklyn splits it into chapters, keeps the bold and italics, and you can re-export it in every format.
