Real-time captions for live streams and online meetings, translated into 100+ languages. Show them on screen in your stream on any platform, or let every viewer and participant read live subtitles in their own language.
Live captions with AI translation turn the speech in a live stream or online meeting into captions in real time and translate them into other languages. With Klassifier, the captions appear on screen in your stream through a transparent caption overlay you add in OBS, vMix, StreamYard or a similar tool, so they work on YouTube, Facebook, Instagram, LinkedIn, TikTok, WeChat and any RTMP platform. Viewers can also open a caption link to read along in their own language, and meeting participants get subtitles in their language.
Viewers and meeting participants come from everywhere, but most live streams and meetings run in a single language. Many streaming platforms offer no closed captions for live video at all, so people who don't speak the language, or watch without sound, miss what is said.
Klassifier recognizes the speech in your stream or meeting as it is spoken, translates it with AI and shows it as live captions: on screen in your stream through a caption overlay, as native YouTube captions, on a caption link viewers open on their own device, or as subtitles in each meeting participant's language.
Add the caption overlay as a browser source in OBS, vMix, StreamYard or a similar tool. The captions become part of your video, so they show up on every platform, including those without caption support.
Speech is recognized as it is spoken and translated into the language you choose, with a short delay behind the speaker.
Show only the translated captions, or the original words and the translation on screen at the same time.
