Upload a Japanese EPUB and get the first fifteen pages back in Chinese. The two languages share thousands of characters and disagree about what a good many of them mean, which makes this pair deceptive rather than easy.
The first 15 pages of text are sent to our server to be translated. The file itself stays on your device.
手紙 is a letter in Japanese and toilet paper in Chinese. 勉強 is studying in Japanese and doing something reluctantly in Chinese. 汽車 is a train in Japanese and a car in Chinese. A Chinese reader can look at a Japanese page, recognise most of the characters and come away with a confident, wrong impression — and a translator that copies characters across rather than reading the sentence produces exactly that, at scale.
Underneath the shared script the grammars have nothing in common. Japanese puts the verb last and hangs particles and conjugations off it; Chinese puts the verb in the middle and inflects nothing. A Japanese sentence has to be understood and rebuilt, not converted.
The model reads the whole book first, fixing names, recurring terms, tone and register before translating a word — which is what keeps a technical term from being rendered three ways across a sample.
A DRM-free EPUB. The file stays on your device; only the text of the sample is sent.
Names and recurring terms are fixed once, so a compound is not translated one way in chapter one and another in chapter six.
About 4,500 words, rebuilt as Chinese sentences rather than character-substituted.
A complete EPUB with the book's own styling. CJK text renders as the book intended.
Honorifics flatten. Chinese has no counterpart to keigo. Deference becomes word choice and phrasing, and some of it is lost.
Vertical becomes horizontal where the target needs it. The file keeps its own stylesheet, but a Japanese book set vertically and read as Chinese will look unfamiliar either way.
Fifteen pages, not the book. About 4,500 words.
The text is sent to a server and discarded when the job finishes.
They make it look easier, which is the danger. A large set of compounds mean different things in the two languages, so the translation reads the sentence and renders the meaning rather than carrying the characters straight across.
Simplified by default. Whichever is used, it stays the same for the whole sample rather than changing partway through.
It becomes register: how formally the sentence is built, what people are called, whether a title is used. Chinese has no grammatical politeness layer, so there is nowhere else for it to go.
About 4,500 words, roughly fifteen pages, five books a day per person.
