Yes, to start: translating text on your own device is free, with no account. Paid plans cover larger document volumes. The language pack itself is a one-time download.

Does my text get uploaded?

No. After the language pack downloads once, translation runs on your machine. There is no server to send text to — that path was removed in August 2026, so a difficult sentence cannot quietly be sent away either.

Does it work offline?

Yes, once the language pack is installed. That is the same thing as the privacy answer: a translator that needs no network cannot be one that uploads your text.

We publish measured COMET scores for the pairs we have benchmarked, each over 200 sentences of the standard FLORES-200 test set, rather than claiming a percentage. Pairs we have not measured get no number, because an estimate presented as a measurement would be a guess.

Do I need an account?

Not to translate text. An account is for syncing your glossary, keeping history across devices and for paid plans.

Languages · measured pair

French to English

Translate French into English on your own machine. After the language pack downloads once, nothing you translate is sent anywhere — there is no server to send it to.

How good is it, measured

COMET 88.1 for French → English, over 200 sentences of the FLORES-200 test set, with the checks running — the recipe that ships. At that score it reads naturally; you would edit wording, not meaning.

COMET is a standard automatic measure of translation quality, not a percentage of words correct; it is the number machine-translation research reports, which is why we report it rather than a figure of our own devising. We publish it for the 45 pairs we have actually run. A pair we have not measured gets no page and no number, because an interpolated score would be a guess presented as a fact.

What you can translate

Text — type, paste or dictate, and read it back in English.
Documents — Word, PowerPoint, Excel, EPUB and subtitles, with the formatting kept rather than flattened.
PDFs — including scanned ones, read on the device.
Pictures — photograph a sign or a menu in French and read it in English.

Why it stays on your device

The engine and the language pack are downloaded once and run locally. There is no French-to-English API call behind this page: the server rung was removed in August 2026, so a hard sentence cannot quietly be sent away to be handled. That matters most for the documents people actually translate — contracts, medical letters, filings. The privacy model says exactly what does and does not leave, and the security page covers the rest.

What is checked before you see it

Each sentence is drafted, then checked for the failures that change meaning rather than style: a dropped negation, a changed number or amount, a name that went missing, a date that shifted. Where a check is not satisfied the sentence is redrafted. French and English are covered by the language-specific tables built for 18 languages. The status line names the step it is on, and anything it could not settle is shown to you rather than hidden.

The other direction, and each language on its own

English to French — measured separately; the score differs by direction.
French on Traxlate — script, voices, picture reading and what else is supported.
English on Traxlate — the same, for the target.

Translating text on your own device

Type, paste or dictate into the box above and the translation comes back from an engine running on this machine. 66 languages, every pair between them, from one language pack that downloads once. Nothing you type is sent anywhere — not the easy sentences and not the hard ones, because there is no server behind this page to send them to.

That matters most for the things people actually paste into a translator: a contract clause, a medical letter, a message from a lawyer, a passage from work they are not allowed to share. With a browser-based translator those all become someone else's server logs. Here they stay on your computer, and you can check that by turning the network off and translating anyway.

What happens to a sentence

The text is split into sentences and each one is drafted, then checked for the failures that change meaning rather than style: a dropped negation, a changed number or amount, a name that went missing, a date that shifted. Where a check is not satisfied the sentence is redrafted. The status line names the step it is on, and anything the checks could not settle is shown to you rather than quietly hidden — a translation you cannot trust is worse than one that tells you where it is unsure.

Beyond plain text

Documents — Word, PowerPoint, Excel, EPUB and subtitle files, with formatting, tables and structure kept rather than flattened.
PDFs — including scanned ones, read on the device.
Pictures and the camera — photograph a sign, a menu or a label and read it in your language.
Subtitles and dubbing — transcribe a video, translate it, and speak it with an on-device voice.

Pairs we have measured

Each of these has been run over 200 sentences of the FLORES-200 test set, and its page prints the COMET score that came back. Every other pair translates just as well in the app — it simply has no page here, because a number we have not measured would be a guess.

All 66 languages and 45 measured pairs.
