You've got Project Hail Mary by Andy Weir as an English .epub, but you'd rather read it in your own language and can't find an edition you can actually get. Whether an official translation reached your language late, went out of stock, or never arrived, translating the copy you already own lets you read the book now instead of waiting.
EPUBTranslator takes the EPUB you have, translates it in context with a large language model, and returns a clean .epub — chapters, footnotes, and the table of contents rebuilt in place.
Project Hail Mary is full of science, invented terms, and a very particular narrator voice. A rushed machine translation mangles all three; a context-aware model keeps the terminology and tone consistent from the first page to the last. If there's no official edition in your language that you can buy, a careful AI translation of your own EPUB is the practical way to read it in your language.
Drop the .epub you own onto the box above. It's parsed in your browser to estimate length and price — nothing is charged yet, and there's a free preview first.
Pick Vietnamese, Spanish, Polish, German, or another language. Each block is translated in context so the invented science terms and the narrator's voice stay consistent across the whole novel.
Pay once for the book — no subscription — and download the finished .epub. Want the English on the page too? Choose the bilingual mode for a side-by-side edition.
This is AI translation, not a publisher's hand-edited edition. It reads smoothly and keeps terminology stable, but where an official translation exists in your language, that remains the reference version. Translate the free preview first and judge the real pages before you pay.

For some languages yes, for others no or hard to find. Where an official edition is available, that's the best option. Where it isn't, translating the EPUB you own lets you read it in your language today.
