Add live captions to your mobile streams on TikTok Live, Instagram Live, and YouTube — whether you're streaming from your phone or routing through a PC setup.
Start Free TrialPhone streaming has exploded as a content format — IRL streams, cooking streams, travel content, and mobile gaming all frequently originate from a phone camera. Adding captions to phone streams is slightly more involved than desktop streaming but very achievable with the right setup.
The most reliable approach for phone stream captions is routing your mobile stream through a PC running OBS. This can be done via OBS's RTMP relay or virtual camera tools that capture your phone output. Once in OBS, StreamTranslate adds captions as a browser source overlay exactly as it does for any other stream format.
For direct phone streaming apps, some IRL streaming tools allow browser overlays that can incorporate StreamTranslate's caption overlay. Check our setup guide for the most current phone streaming options.
