How to translate Twitch streams in real time
Capture a Twitch stream tab in Chrome or Edge, set the streamer’s language, and read translated captions while the broadcast continues.
To translate a Twitch stream, watch it in Chrome or Edge and capture the stream tab with TanLens. The extension hears the stream audio, transcribes the speech and shows a translation under each line. When you stop, the transcript is available to edit and export instead of disappearing with the chat.
01Pick the stream tab, not the whole desktop
Open the channel, start playback, and press Start in the extension while that tab is active. Capturing one tab keeps music from another tab out of the transcript and avoids picking up system notifications. Set the source language to auto-detect if the streamer mixes languages, or lock it for a single-language channel. Game audio and alerts still reach the recognizer, so a streamer who whispers during loud gameplay will be harder to transcribe than one who talks into a proper microphone.
02Keep the useful parts
Stop the session when the segment you care about ends, save the transcript, then search for the quote you want to clip. Fix the streamer’s name and the game or product names first, because those are the terms viewers will search for. Export SRT for a clip editor, VTT for a web player, or TXT for a summary. TanLens does not download the VOD or bypass channel permissions; it only keeps the text you explicitly save.
