Translate an EPUB and read it in your language

Upload the book and get a translation that reads in order, with navigation across the chapters we recognise. Want to listen on the move? Add narration to the translation.

Translate an EPUB

A book you can come back to

Translate the EPUB once and come back to it whenever it suits you — carry on reading in the evening, or switch to audio on the move. The file stays in your account, with no second translation and no hunting down the ebook again.

What you get

A translated EPUB for your e-reader

Download the translated EPUB and read it in your usual app — headings, paragraphs and movement between chapters included. The navigation table of contents is built from the book headings we recognise.

Reading without repeated boilerplate

SonikaAI strips out the running heads and page numbers it recognises so they do not interrupt your reading. The table of contents stays available so you can jump between chapters, but it is not inserted as a chapter of its own by default.

Text and audio from one upload

Choose translation with narration to get both text and audio from a single upload. If SonikaAI recognises the chapters, you get one M4A file with chapter marks; if not, an MP3.

What the audiobook will contain

To listen without interruptions, choose main text — no recognised boilerplate, notes or bibliographic references. If you want them, choose full narration.

When it is worth checking a sample first

Book mode is built for reading text in sequence. If your EPUB depends on tables, diagrams or a complex layout, check a sample first: the layout is not guaranteed to survive. EPUB always goes through Book mode — there is no Book/Document choice as there is for PDF, and no page range either.

Before you translate

How much you can translate and narrate depends on your plan and how you pay. For narration it may cover fewer pages than for translation alone.

Translate and narrate books and documents

Translate a book or document and get the audio in the same language as the text, from a single upload. Listen to study and work material whenever it suits you.

Narrate text, books and documents online

Turn a PDF, Word file, EPUB or plain text into audio without translating it. Choose a voice, pick main text or full narration, and download the finished file.

Book translation services compared

For a whole book, compare the translation, the formats you can read it in, and how you get an audio version — then pick what fits your task.
