StreamTranslate runs in the cloud — paste one URL into OBS and go live. Works on any laptop or PC. Unlike local AI tools, there's nothing to install or configure.
为您的OBS直播添加翻译字幕
An OBS subtitle overlay is a browser source layer that displays live captions on top of your stream. Unlike burned-in captions (which require post-processing), an OBS subtitle overlay works in real time and shows text directly on your broadcast.
StreamTranslate takes this a step further: it not only transcribes what you say in real time, it also translates those words into your target language — so your viewers see translated subtitles live, as you speak. One overlay URL. Drop it into OBS. Done.
