Twitch Studio is built for simplicity — which means live captions, real-time translation, and subtitle overlays are completely missing. StreamTranslate fills that gap. Paste one URL as a browser source and you're broadcasting with subtitles in under 60 seconds.
No downloads. No API keys. Works in Twitch Studio, OBS, Streamlabs, and more.

Twitch's global audience watches in every language — but most Twitch Studio streamers broadcast monolingually. Live captions and translation directly increase your accessible audience. Viewers who are deaf or hard of hearing, watching without audio, or browsing in a second language can now follow your stream without any effort on your part.
Language communities also drive discovery. A translated Spanish caption track means Spanish-language clip sites, Discord servers, and communities can engage with your content. Twitch's own research shows international viewers have strong retention when content is accessible in their language. StreamTranslate handles this automatically — you speak, and your words appear in every language you've configured.
