Upload a Japanese EPUB and get the first fifteen pages back in Korean. These two languages line up so closely that a word-for-word translation almost works — which is exactly how bad translations between them get made.
The first 15 pages of text are sent to our server to be translated. The file itself stays on your device.
Japanese and Korean put the verb at the end, mark grammatical roles with particles, conjugate for politeness and build their formal vocabulary from the same Chinese roots. You can very often replace each word in a Japanese sentence with its Korean counterpart and get a grammatical Korean sentence. It will also read, unmistakably, as a translation from Japanese — because the particles do not overlap exactly, the honorific systems draw their lines in different places, and Korean prefers different constructions where both are available.
That is the specific risk in this pair, and it does not exist between languages far enough apart to force a rewrite. Here the translation has to resist the easy path.
Reading the whole book first sets the register once — the cast, their relationships, the names, the recurring terms — so the sample reads as Korean prose rather than as Japanese with Korean words.
A DRM-free EPUB. The file stays on your device; only the text of the sample is sent.
The cast and their relationships are mapped once, then rendered in one consistent set of Korean speech levels.
About 4,500 words, written as Korean sentences rather than Japanese sentences with substituted words.
A complete EPUB with the book's own styling. Hangul renders in essentially every reader.
The honorific systems are similar, not identical. Japanese and Korean both grade politeness in the verb, but they grade it differently, so the mapping is a judgement made once rather than a lookup.
Ruby is not carried across. Furigana is reading help for Japanese and has no function in Korean.
Fifteen pages, not the book. About 4,500 words.
The text is sent to a server and discarded when the job finishes.
Structurally, yes — the grammars line up more closely than almost any other pair of major languages. The risk that comes with it is translationese: Japanese-shaped Korean that is grammatical and obviously translated, which is what the register set from the whole book is there to prevent.
As a deliberate mapping, decided once. Both languages grade politeness in the verb, but the grades do not line up one to one, so the pairing is chosen for the book and then held rather than re-derived in every scene.
Yes, transliterated into Hangul, with the same spelling on every appearance — which is one of the things the model reads the whole book to fix before translating.
About 4,500 words, roughly fifteen pages, five books a day per person.
