How whole-work import works
- Paste a public AO3 work or chapter URL.
- Preview the detected title, author, and ordered chapter list.
- Import all chapters in order with visible progress. Stop any time and keep the chapters that already arrived.
- Set the cover and formatting, then export the binder as EPUB.
When fetching is blocked
Whole-work import supports publicly accessible works only. Login-restricted works, adult-consent gates that cannot be confirmed automatically, and rate-limited pages will not import. In those cases, copy the chapter text from your browser and use Manual Entry instead — the EPUB output is the same.
