Upload a Vietnamese EPUB and get the first fifteen pages back in Korean. Korean needs to know the relationship before it can conjugate a verb — and Vietnamese has already written that relationship into every pronoun.
The first 15 pages of text are sent to our server to be translated. The file itself stays on your device.
This is the reverse of the usual problem. Translating into Korean from English means inferring a relationship the source never stated; translating into Korean from Vietnamese means reading one that is stated outright, in every sentence, by the choice of anh, chị, em or cô. The speech level follows from it rather than being guessed at.
The correspondence is not mechanical, though. Korean also marks whether the speaker is male or female in some address terms, and it distinguishes levels of formality that Vietnamese handles with other words entirely. The mapping has to be chosen once and held for the whole book.
The model reads the entire text first and builds that mapping, along with the names, the recurring terms and the tone, before translating a word of the sample.
A DRM-free EPUB. The file stays on your device; only the text of the sample is sent.
The pronoun relationships are read from the Vietnamese and mapped once onto Korean speech levels.
About 4,500 words as a complete EPUB. Hangul renders in essentially every reader.
Names lose their tones. A Vietnamese name written in Hangul keeps its shape and loses its diacritics; the same spelling is used throughout, which is the part that can be guaranteed.
The mapping is a choice. Vietnamese and Korean both encode relationships, but they do not divide them along the same lines, so some pairings are judgement rather than equivalence.
Fifteen pages, not the book — about 4,500 words — and the text is sent to a server and discarded when the job ends.
By reading the relationship they declare. anh/chị/em state who is older and how close two people are, which is precisely what a Korean verb ending encodes — so the mapping is grounded in the text rather than inferred from nothing, and it is fixed once from the whole book.
Yes, for formal and abstract vocabulary. Both languages built that layer from the same Chinese roots, so many academic and technical terms have direct counterparts. Everyday words diverge, so the benefit is clearest in non-fiction.
Yes. Only the text changes; the book's own fonts and stylesheets are left alone, and Hangul is supported in every modern reader and on Kindle.
About 4,500 words, roughly fifteen pages, five books a day.
