LiveTL is a Chrome extension that VIEWERS install to translate chat on YouTube/Twitch streams. StreamTranslate is the streamer-side overlay — the BROADCASTER installs once and every viewer sees translated captions on the stream itself.

LiveTL is a Chrome extension. Each VIEWER installs it, configures their target language, and translates chat messages on YouTube/Twitch streams (heavily used for VTuber chat). It works great when viewers are technical and willing to install extensions.
StreamTranslate is the opposite — the STREAMER installs it once (as an OBS browser source), and every viewer sees translated captions on the broadcast video itself. No per-viewer install. No fragmented browser support.
LiveTL translates the CHAT — the messages typed by viewers. StreamTranslate translates the STREAM — what the streamer says.
For most streamers, what you SAY matters more than chat noise. Viewers come for gameplay commentary, conversation, the streamer\u2019s voice. LiveTL helps with chat; StreamTranslate makes the core content accessible.
