A | 文 Bilingual EPUB Toolkit

Merge two monolingual EPUBs into one tap-to-reveal bilingual book -- or split one back apart.

Two monolingual EPUBs become one facing-text book: a paragraph from A, the matching paragraph from B right below it, blurred until you tap it.

Upload the .epub file itself. An archive containing a book is also accepted. Files protected by DRM cannot be read by any tool of this kind.
