Text translator
Translate text without sending it anywhere. The language model runs inside your browser, so it works with no signal, no account, and no third party reading what you typed.
About this translator
Every mainstream translation service sends your words to a server. That is fine for a restaurant menu and a poor idea for a contract, a medical letter, or an immigration document — and it fails completely at the moment you most need it, which is usually a foreign country with no signal.
This runs the translation model inside your browser. The model downloads once, roughly 140MB per direction, and after that translation works with the network switched off entirely. Nothing you type is ever transmitted.
Translating into English detects the source language automatically and handles over 200 of them. Translating out of English asks you to pick a target. Quality is strongest for widely-spoken languages and falls off for less-represented ones, which is a property of the training data rather than something a setting can fix.
It is machine translation: it carries meaning across reliably and misses idiom, register, and nuance. For anything where being wrong has consequences, have a human check it. This is not a certified translation.
Common questions
- Does this work without an internet connection?
- Yes, once the model has downloaded. The first translation in each direction fetches about 140MB, and after that your browser has everything it needs. You can go offline entirely and it keeps working.
- Is my text sent anywhere?
- No. The model runs on your own machine and no text leaves the browser. The only network request is the one-time model download, which contains no data of yours.
- Which languages are supported?
- Into English, over 200 source languages with automatic detection. Out of English, a curated list of the languages the model handles well. Coverage is broad; quality is best for widely-spoken languages.
- How does it compare to Google Translate?
- Google is better, particularly on idiom and less-common languages, because it runs a far larger model on their hardware. This one trades some quality for the things Google cannot offer: it works with no signal and it never sees your text.
- Can I translate a document?
- Paste the text in. Direct file translation and translating text from other applications are not things a browser can do — a web page cannot read your other windows.
- Why is long text split up?
- The model has a fixed input window and silently truncates anything longer rather than reporting an error. Text is split at sentence boundaries so nothing is quietly lost.
