Translate a Spanish book into French

Upload a Spanish EPUB and get the first fifteen pages back in French. Two close cousins, which means the formality survives intact and the false friends are more dangerous than usual.

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

The good news first: both languages mark formality in the pronoun, so the tú/usted distinction maps onto tu/vous almost directly. None of the guesswork that translating into French from English requires is needed here — the source already says who is close to whom.

The risk sits in the vocabulary that looks identical. Embarazada is pregnant; embarrassée is embarrassed. Largo is long; large is wide. Entender is to understand; entendre is to hear. A translation confident about cognates produces sentences that are grammatical, fluent and occasionally about something else entirely — the hardest kind of error to catch, because nothing reads as wrong.

The past tenses diverge too: the two languages use their compound and simple pasts differently, so a sequence of events can come out of step. Reading the whole book first sets the narrative register once, which is what keeps it aligned.

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 fixed once, from the complete text.

  3. The first 15 pages come back in French

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

  4. Download, or read it here

    A complete EPUB using French punctuation conventions — guillemets and dialogue dashes, not Spanish ones.

Honest limits

Cognates are checked, not trusted. That is the whole discipline of this pair, and it is where a careless translation goes wrong invisibly.

The past tenses do not align. French and Spanish use their compound and simple pasts differently, so the mapping is a decision made once for the book rather than sentence by sentence.

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

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

Questions

Does tú/usted map onto tu/vous?

Yes, closely — which is one of the reasons this pair works better than either language paired with English. The relationship is stated in the source, so it does not have to be inferred, and reading the whole book first keeps it consistent.

What about false friends?

They are the main risk in this direction, and they are handled by translating what the sentence means rather than what the word resembles. It is worth spot-checking a few in the sample; they are the failure mode that reads perfectly.

Is the French punctuated the French way?

Yes — guillemets and dashes for dialogue rather than the Spanish conventions, because a French book punctuated like a Spanish one announces itself as a machine translation on the first page.

How much is free?

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