Adding captions to a live stream used to require technical setup and expensive software. In 2026, StreamTranslate does it in under 2 minutes — a browser source in OBS, and you are live with real-time AI captions in 125+ languages.
Try StreamTranslate FreeThe most widely used approach: add StreamTranslate as a browser source in OBS. No encoding changes, no plugins, zero performance impact. Captions appear as an overlay on your stream, visible to all viewers.
Captions increase average viewer watch time by up to 40%. They make your content accessible to deaf and hard-of-hearing viewers. They open your stream to non-English speakers worldwide. Platforms algorithmically favor accessible content.
StreamTranslate does both — it transcribes your speech and simultaneously translates into 125+ languages. Viewers can see captions in their native language while you speak in yours.
