Some books never get an edition in the language you read.
I built EPUB Translator for readers who already have an ebook in another language and want to translate the whole book without copying chapters into a chat window.
Here s how it works:
- Select your EPUB in a phone or desktop browser.
- Sign in and see the exact quote for your file.
- Choose a language and pay once.
- Download translated-only and bilingual EPUBs, both included.
The bilingual edition puts each original paragraph above its translation, so you can compare as you read.
Pricing starts at $3.99 per book, with no subscription or personal API key required.
It s AI translation, so mistakes can happen. Use DRM-free files you have the right to upload, and check passages that matter.

What book would you translate, and into which language? What would you want to see before paying clearer pricing, or something else?
Hi Product Hunt! I'm Chase, the maker of EPUB Translator.
This is for the reader who already has one book in another language and wants to read the whole thing as an ebook. Pasting passages into a chat window leaves you with a lot of copying and reassembly. The idea here is to keep the book together.
You can use it in a phone or desktop browser. Select your EPUB, sign in, and see the quote for that file. Click Start Translation, choose the target language, then pay once. When the translation finishes, download either the translated-only EPUB or the bilingual EPUB; both are included. The bilingual version places each original paragraph above its translation.
Pricing starts at $3.99 per book. There is no subscription, translation app to install or personal API key to configure.
A few limits upfront: use DRM-free files you have the right to upload. AI can make mistakes, so check passages that matter. Text-based PDFs can also become EPUBs; this is not a scanned-PDF OCR service.
For Product Hunt readers, PRODUCTHUNT20 offers up to 20% off one eligible translation, capped at $5. The $3.99 minimum still applies. First 100 claims, one per person; the coupon lasts 30 days after claiming. Sign in on the site to claim it.
What book and language pair would you use this for? I'd especially like feedback on whether the quote and bilingual output make the purchase decision clear. Please don't post copyrighted book files or private manuscripts in the comments.
Thanks for taking a look!
