Chinese to English

How good is it, measured

COMET 85.0 for Chinese → 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.

Five real translations, unedited

These sentences come from FLORES-200, the public test set that translation research is measured on. They were chosen before anything was translated — the same five on every pair page — and each is shown exactly as Traxlate returned it on an RTX 3070, next to the translation a professional translator wrote for the same sentence.

A different word from the reference is not an error: two good translators rarely match word for word. What to look for is whether the meaning, the numbers and the names came through.

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