Translator (In-Browser AI)
AIRuns On Your DeviceTranslate text between English, Spanish, French, and Japanese with a real translation model running in your browser — no uploads.
Each direction downloads its own quantized OPUS-MT model (~80 MB, cached afterwards — later sessions work offline; a download this size may use significant RAM while running). Your text is never uploaded — only the model files come from a CDN. Only directions that actually run are listed; Japanese is one-way (Japanese → English) because no browser-ready English → Japanese model exists yet — we label that honestly rather than pretend.
Private Translator — Real Machine Translation in Your Browser
Translate text with genuine neural machine translation (OPUS-MT) that runs entirely inside your browser using WebGPU or WASM. Your text is never uploaded to a translation server — unlike typical online translators, this one keeps confidential drafts, emails, and documents strictly on your device.
Each language pair (English↔Spanish, English↔French, Japanese→English) uses its own ~80 MB quantized model, downloaded once on first use and cached — after that it works offline. The offered pairs are exactly the ones that load and run; Japanese→English is one-way because no browser-ready en→ja model exists, and we label that honestly rather than pretending.
