You speak in your native language and viewers see accurate translated subtitles on your stream in real time. Everything runs in the cloud, so there is zero CPU or GPU overhead on your streaming PC.
The system uses advanced AI speech recognition for fast, accurate transcription, then races multiple translation engines to return the best result in under 500ms. The translated text renders as a styled subtitle overlay via an OBS browser source — no plugins, no third-party software, and no browser extension on the viewer side.
Setup is simple: sign up at streamtranslate.live, pick your speaking language and your target subtitle language, copy your personal browser source URL, and paste it into OBS as a new Browser Source. Position it at the bottom of your scene and go live. Pro and Elite plans support dual-language output so you can serve two audiences at once.
Also supports IRL with Moblin and the OBS audio plugin, including home and cloud OBS setups such as IRL Toolkit.
Use an OBS receiver for IRL Pro, Larix Broadcaster, PRISM Live Mobile or TVU Go. Cloud providers may need to install the plugin on your server.
