AI on the Listener's Phone
Opus-MT translation models run inside each viewer's browser via Transformers.js. No cloud service, no per-minute fees, unlimited listeners.
5 Reading Languages
English, Español, Français, Deutsch, and Italiano — each viewer picks independently. The ~40 MB model downloads once and is cached offline.
Text-to-Speech
The phone can read the translation aloud through earphones — replacing dedicated translation-receiver hardware for visually-impaired listeners.
Interface in 9 Languages
The app shell itself is localized into nine languages and follows each phone automatically.
