Twitch Chat & Stream Translation, in One Tool

If you stream in English but pull viewers from Brazil, Spain, France, or Korea — they read chat in their language. Half your chat is replies they don't understand. Half their messages get ignored because YOU don't understand them.

StreamTranslate gives you two things at once:

• Live translated subtitles on your stream — international viewers follow what you say, in their language, in real time
• Translation overlays for chat — opt-in chat translation visible only to viewers who want it

1. Sign up — Free Plan with 3 hours every month, card required for the Free Plan; no payment unless you upgrade.
2. Generate OBS browser source URL — pick what language(s) you want subtitles in.
3. Drag URL into OBS as a Browser Source on your active scene.
4. Optional: link your Twitch via the dashboard to enable chat translation overlays.

That's it. International chat replies start landing within minutes of going live with translated captions.

Does StreamTranslate translate Twitch chat?

Yes — both stream audio (your voice into translated subtitles) and chat messages (translation overlay). Most competitors do only one.

Do I need a bot install or chat connection?

No bot install required. Chat translation is opt-in via Twitch OAuth from the dashboard.

Will viewers see translated chat messages?

Yes — through an opt-in translation overlay. Viewers who want translation enable it on their end; others see chat as-is.

How many languages?

65 target languages including Spanish, Portuguese, French, German, Japanese, Korean, Mandarin, Arabic, Hindi, Russian.

Is this different from Twitch native auto-translation?

Yes. Twitch has no native chat or stream auto-translation. StreamTranslate fills that gap with a 3rd-party browser source overlay that runs entirely cloud-side.

Will it slow down my stream?

No. Browser source uses near-zero CPU. All translation happens cloud-side.
