A Twitch translation overlay lets international viewers read your stream in their own language — in real time, as you speak. StreamTranslate does this via OBS browser source: no Twitch extension, no plugin, no app to install on your PC.
Why Twitch Streamers Use Translation Overlays
75% of Twitch viewers are outside the US. If you stream in English, you're already losing most of your potential audience to the language barrier. A real-time translation overlay means Spanish, Portuguese, Japanese, Korean, and Arabic viewers can follow your stream live — without you changing anything about how you stream.
Top multilingual streamers see 20–40% audience growth after adding translation. International viewers are more loyal, more likely to subscribe, and less likely to churn compared to domestic viewers.
