Languages · measured pair
English to Tamil
Translate English into Tamil 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 86.5 for English → Tamil, over 200 sentences of the FLORES-200 test set, from the draft pass alone. 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
Why it stays on your device
The engine and the language pack are downloaded once and run locally. There is no English-to-Tamil 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. English and Tamil 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
- Tamil → English works in the app, but we have not benchmarked that direction yet, so there is no page claiming a number for it.
- English on Traxlate — script, voices, picture reading and what else is supported.
- Tamil on Traxlate — the same, for the target.
