About StreamTranslate
Breaking language barriers in live streaming — one subtitle at a time.
Our Mission
Live streaming connects millions of people worldwide, but language still divides them. A viewer in Tokyo can't follow an English-speaking streamer on Twitch, YouTube, X, and TikTok. A Brazilian fan misses the best moments from a Korean gaming stream. We built StreamTranslate to fix that.
Our mission is simple: make every live stream accessible to every viewer, in every language, in real time. No delays. No complicated setups. Just paste a browser source URL into OBS, pick your languages, and go live with translated subtitles your entire audience can read.
What We Do
StreamTranslate delivers real-time translated subtitles for live streamers on Twitch, YouTube, X, and TikTok, and Kick. We support 28+ languages with sub-2-second latency. Streamers set it up in under 60 seconds — no plugins, no downloads, no technical knowledge required.
Whether you're a solo streamer trying to grow internationally or a professional creator looking to reach new markets, StreamTranslate handles the hard part so you can focus on your content.
Our Technology
We use cutting-edge AI speech recognition powered by Deepgram — one of the fastest and most accurate real-time transcription engines available. Your speech is transcribed with 95%+ accuracy and translated using neural machine translation models, then displayed as clean subtitles on your stream overlay.
Everything runs in the cloud. No local processing, no GPU requirements, no CPU drain. Your stream performance stays exactly the same.
The Team
We're a small team of developers, designers, and streamers who got tired of watching great content get ignored because of language barriers. We've spent years in the streaming space — as viewers, as creators, and as builders — and we knew the existing tools weren't cutting it.
StreamTranslate was born from the belief that the best tools are the ones you forget you're using. Setup should take seconds, not hours. Subtitles should just work. And every streamer — from affiliate to partner to hobbyist — should be able to reach a global audience.
