How good is it?
The translator uses Opus-MT models from the University of Helsinki, a widely used open-source translation project. They handle everyday writing well. Like any machine translation, they can miss tone, idioms and specialist terms, so have a fluent speaker check anything official.
Why use a translator that runs in your browser?
Popular online translators send your text to their servers, which isn't ideal for contracts, medical letters or private messages. Here the model runs on your device, so the text never leaves it, and it keeps working offline once the language pair has downloaded.
Language pairs available
English to and from Spanish, French, German, Italian, Hindi, Arabic, Chinese, Russian, Indonesian, Vietnamese and Dutch, plus Japanese, Korean, Turkish, Polish and Ukrainian into English. More pairs will be added.

Is my text uploaded?
No. Translation happens on your device.
Why do some directions only go into English?
