Translate an English book into Ukrainian

Upload an English EPUB and get the first fifteen pages back in Ukrainian. When one character calls another by name, Ukrainian changes the name — and a translation that does not is instantly recognisable as machine output.

The first 15 pages of text are sent to our server to be translated. The file itself stays on your device.

Ukrainian keeps the vocative case, and it is not optional or archaic: addressing Оксана means saying Оксано. Dialogue is full of people calling each other by name, so this turns up constantly, and leaving every name in its dictionary form is the single clearest tell that no one who speaks the language was involved.

Names decline in the other six cases too, borrowed English ones included, which means a name cannot be substituted from a glossary — it has to be written into the sentence.

And the transliteration has to be settled once. Half the English names in a novel have more than one plausible Cyrillic spelling, and a different choice in chapter six introduces a character who does not exist. The model reads the whole book first and fixes the names, the terms, the tone and the ти/ви map before anything is translated.

How it works

  1. Choose your English EPUB

    A DRM-free EPUB. The file stays on your device; only the text of the sample is sent.

  2. The model reads the whole book

    Each name gets one Cyrillic spelling, chosen once and used for the whole book.

  3. The first 15 pages come back in Ukrainian

    About 4,500 words, translated as whole sentences so names take the case the sentence requires — including the vocative in dialogue.

  4. Download, or read it here

    A complete EPUB. Ukrainian Cyrillic, including і, ї, є and ґ, renders in every modern reader.

What this free tool does not do

Fifteen pages, not the book. About 4,500 words, counted in words.

Transliteration follows convention, not fandom. If a name already has an established Ukrainian spelling among readers of a particular book, the model may not know it — but it will not contradict itself.

ти or ви is inferred. English marked neither. The guide makes the choice consistent across the sample.

The text is sent to a server and discarded when the job finishes.

Questions

Is the vocative case used when characters address each other?

Yes, and it is worth checking first in the sample. Ukrainian uses the vocative in ordinary speech, so a novel full of dialogue uses it constantly — and a translation that leaves every name in its base form reads as foreign from the first line.

Are names declined in the other cases too?

Yes. Names are written into sentences rather than pasted in from a list, which is what lets them take the case the grammar requires, and reading the whole book first is what keeps the chosen spelling identical throughout.

Will Ukrainian Cyrillic display properly?

Yes, in any modern reader and on Kindle. The letters specific to Ukrainian are ordinary Unicode text and the file keeps the book's own stylesheet.

How much is free?

About 4,500 words, roughly fifteen pages, five books a day per person.
