Translate a Spanish book into Italian

Upload a Spanish EPUB and get the first fifteen pages back in Italian. Two languages that share a formality system, a diminutive system and a large number of words that do not mean the same thing.

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

What transfers well here transfers unusually well. Both languages mark formality in the pronoun, so usted becomes Lei without inference. Both build affection and contempt into noun endings, so a Spanish -ito can become an Italian -ino and keep its tone — something that simply cannot survive into English, where a suffix has to become an adjective.

Burro is a donkey in Spanish and butter in Italian. Caldo is broth in Spanish and hot in Italian. Salir is to go out and salire is to go up. The overlap is enormous and the disagreements are quiet, so the translation follows what the sentence means rather than what the word resembles.

Reading the whole book first fixes the names, the recurring terms and the narrative register — including whether the narration uses the literary past, which both languages have and use differently.

How it works

  1. Choose your Spanish EPUB

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

  2. The model reads the whole book

    Names, terms and the narrative register are settled once, from the complete text.

  3. The first 15 pages come back in Italian

    About 4,500 words, translated through meaning rather than through cognates.

  4. Download, or read it here

    A complete EPUB with the book's own styling. Accents and elisions render everywhere.

Honest limits

Cognates are the risk. Two languages this close share thousands of words and disagree about enough of them to spoil a chapter quietly.

The literary pasts do not align. Spanish and Italian both have one, and they use them differently, so the choice is made once for the book.

Fifteen pages, not the book. About 4,500 words.

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

Questions

Do diminutives survive?

Yes, and this is one of the few pairs where they can. Both languages express affection, smallness and scorn in noun endings, so a Spanish diminutive becomes an Italian one and keeps its tone instead of being flattened into an adjective.

Does usted become Lei?

Yes, directly. The relationship is stated in the Spanish, so it does not have to be inferred — and reading the whole book first keeps the choice consistent across chapters.

How are false friends handled?

By translating the sentence rather than the word. It is worth spot-checking a few in the sample; they are the failure mode that reads perfectly naturally.

How much is free?

About 4,500 words, roughly fifteen pages, five books a day per person.

Translate the whole book

The app runs the same engine across the entire book and can show the Italian next to the Spanish, with your position synced between devices.
