Translate a Chinese book into English

Upload a Chinese EPUB and get the first fifteen pages back in English. The model reads the whole book first, which is the only way names, titles and invented terminology stay the same from chapter to chapter.

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

Chinese fiction punishes paragraph-at-a-time translation harder than most languages, and web novels punish it hardest. A single character's name can be rendered a dozen defensible ways; a cultivation rank or a sect name invented by the author has no dictionary entry at all. Translate chapter three without having seen chapter one and you get a different set of choices, every time.

Reading the entire book first fixes the vocabulary before a word is written: every name, every place, every invented term, recorded once with how it will be rendered throughout.

The other Chinese-specific issue is on the page rather than in the prose. Chinese text needs a font with CJK glyphs, and if the reading app falls back to a Latin-only font every character becomes a box. This tool changes only the text inside the original file and leaves its fonts and stylesheets alone, so a book that displayed correctly still does.

How it works

  1. Choose your Chinese EPUB

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

  2. The model reads the whole book

    Names, titles, sects, ranks and invented terms are fixed once, from the whole book, before translation starts.

  3. The first 15 pages come back in English

    About 4,500 words, translated as continuous prose rather than isolated lines.

  4. Download, or read it here

    A complete EPUB with the original's fonts and styling intact.

What this free tool does not do

Fifteen pages, not the book. The rest stays in Chinese in the same file.

Chengyu lose their weight. A four-character idiom carrying a whole story behind it comes out as a plain English phrase. That is a real loss and no tool avoids it.

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

Classical Chinese is not this tool's job. Modern prose and web fiction translate well; literary Chinese needs a specialist.

Questions

Does it handle Simplified and Traditional?

Both. The source is Chinese either way and nothing in the pipeline cares which script the original used.

How does it deal with invented cultivation terms?

It decides once, from the whole book, and applies that decision throughout the sample. It cannot know a fan-standard rendering the community already agreed on, but it will not contradict itself.

Will the Chinese characters still display in the output file?

Yes. Only the text is replaced; the book's own fonts and stylesheets are untouched, so whatever displayed before still displays.

Is it good enough for web novels?

That is where reading the whole book first pays off most, because web novels are exactly the case with the most invented vocabulary and the least dictionary support.

Translate the whole book

The app translates the entire book with the same engine and keeps the Chinese beside the English, so you can check any line against its source.
