Bilingual Book Builder

Upload a source (original) EPUB and a target (translation) EPUB to create a side‑by‑side bilingual book.

Processing may (and probably will) take hours – you can close this page and return later.

When ready, the bilingual EPUB will be stored for 24 hours.

You can also run this locally, it's way faster if you have a graphic card (but requires model downloading).
