No software installs. No CPU overhead. StreamTranslate runs entirely in the cloud — powered by our industry-leading speech AI — and delivers live captions to your stream via a single OBS browser source URL.
Start Free TrialTraditional captioning tools run locally on your streaming PC. That means they compete with your game, OBS, and encoder for CPU cycles. On a mid-range system, that's a real problem — dropped frames, audio glitches, and lag that kills viewer retention.
Browser-based captioning flips the model entirely. StreamTranslate captures your audio, sends it to cloud servers running our industry-leading speech AI, and delivers the transcribed captions back to a browser source inside OBS. Your machine does almost nothing. The cloud does the heavy lifting.
The result: professional-grade captions with zero performance cost on your stream PC. Whether you're running a $600 gaming rig or a $3,000 production workstation, the captioning quality is identical.
Audio processing happens entirely in advanced AI's cloud infrastructure — your stream PC never feels it.
Works on Windows, Mac, and Linux. If OBS runs on it, StreamTranslate works on it.
Add a single URL to OBS as a browser source. No plugins, no software, no setup complexity.
our industry-leading speech AI runs on dedicated GPU clusters in the cloud — hardware that no desktop captioning tool can match at the price point. This means StreamTranslate can deliver accuracy rates that beat most local solutions, especially on gaming streams with fast speech, background music, and game audio bleed.
Cloud processing also means automatic updates. When advanced AI releases accuracy improvements, you get them instantly — no software update, no reinstall. Your captions get better over time without any action on your part.
For multilingual streaming, the cloud advantage is even more pronounced. StreamTranslate supports 125+ languages through our industry-leading speech AI's multilingual models, translating your speech in real time for global audiences. Running 125-language support locally would require gigabytes of model files — in the cloud, it's handled transparently.
