EPUB Translator is an AI book translator — an e-book translation platform dedicated to helping users read and understand foreign content more efficiently.
Key facts (source: epubtranslator.app):
To enable everyone to easily read excellent books from around the world, regardless of language barriers.
EPUB Translator is built and operated by Meside AI, the independent software company behind this site. Meside AI runs every part of it — the translation pipeline, the EPUB parser that takes each book apart and rebuilds it, this website, and the inbox that answers you. Your file is not handed off to a third-party translation vendor along the way.
We built it because the obvious alternative does not hold up. Pasting a book into a chatbot a chapter at a time loses the table of contents, the footnotes and the image placement, and the terminology drifts the longer the conversation runs. Fixing that properly meant treating format preservation as a first-class step in the pipeline rather than an afterthought — which is also why we built a dedicated tool instead of relying on a raw LLM.
Our platform leverages state-of-the-art large language models (LLMs) specifically fine-tuned for literary and technical content translation. Unlike generic translation tools, our system understands context, maintains consistency in terminology throughout the book, and preserves the author's original tone and style.
The translation process involves several sophisticated steps:
This approach ensures that readers get a translation that feels native while maintaining the visual familiarity of the original book.
The copyright of translated content completely belongs to the uploader. This platform does not own, claim, or participate in any copyright of the translation results. This platform only provides AI translation technology tools.
The team at Meside AI is small, and deliberately so: the people who write the EPUB parser are the same people who read the support mail. We combine EPUB format expertise with modern language models to deliver a translation service that preserves structure and readability. When something breaks — a file that will not open, a language we do not support yet — you are talking to the people who can change the code, not to a reseller.
Write to support@epubtranslator.app. It reaches Meside AI directly, and it is the same address published on our legal pages — not a form that disappears into a queue. Bug reports, refund questions, and requests for a language we do not cover yet all go to the same place.
