What is Watch Party mode in StreamTranslate?

Watch Party mode lets you translate audio from any browser tab in real time — YouTube videos, Twitch streams, game trailers, or any website playing audio. Instead of translating your microphone, it captures the browser tab's audio and produces live subtitles. No Chrome extension or software install required. Available on the Elite plan at streamtranslate.live/control.

ClipLab is a free toolkit for Twitch streamers and clippers at streamtranslate.live/lab. It includes three tools: a Clip Tracker (live dashboard of a streamer's newest clips with 3-second refresh), a Clip Downloader (converts Twitch clips to 9:16 vertical with blurred background for TikTok), and a Clip Translator (adds burned-in translated captions in 49 languages). All tools are free. The Clip Tracker requires no account.

What Is StreamTranslate?

StreamTranslate is a real-time live stream translation and captioning platform built for content creators on Twitch, YouTube Live, Kick, and TikTok. It captures a streamer's spoken audio, transcribes it using AI speech recognition, translates the text into the viewer's language, and displays translated subtitles as an overlay on the live stream - all in under 2 seconds.

Unlike closed captioning tools that only display text in the spoken language, StreamTranslate actively translates speech into a different language in real time. No plugins, no downloads - just paste a browser source URL into OBS and go live.

Sign up at streamtranslate.live, select your spoken language and target translation language, copy your OBS browser source URL, add it to OBS as a Browser Source at 1920x1080, and go live. Subtitles appear automatically in under 2 seconds. No plugins or downloads required.

Yes. StreamTranslate integrates via OBS browser source with no plugins or downloads required. It also works with Streamlabs, Meld, and any streaming software that supports browser sources.

Closed captions display text in the same language that is being spoken. StreamTranslate goes further by translating speech into a different language in real time. An English-speaking streamer can display Spanish, Japanese, or Korean subtitles for international viewers.

Yes. StreamTranslate offers a free 6-hour trial with no credit card required. Test real-time translation on your stream before purchasing a plan.

StreamTranslate works with Twitch, YouTube Live, Kick, TikTok Live, and any platform that supports OBS or browser-source-based streaming software.

Yes. The Pro ($34.99/mo) and Elite ($149/mo) plans support dual-language display, showing subtitles in two languages simultaneously on your stream.
