Translate a live stream while it is running
Real-time translated subtitles over YouTube live streams and videos in the browser, where auto-captions only give you the language being spoken.
Free to start · Works in your browser · Your audio stays private
Auto-captions arrive in the language that is being spoken.
YouTube captions a live broadcast automatically, but that caption track is in the language of the stream. Turning it into your language on a live broadcast is not something a viewer switches on. Trippi listens to the tab and writes the translation underneath, and it behaves the same whether the stream is live, a premiere or an ordinary video.
Why a live stream is harder than a video
A finished video can be given a translated subtitle track by whoever uploaded it. A live stream has no such moment: the words exist for a second and then they are gone, and the person who could add subtitles is the one currently talking.
That is the whole gap. Trippi transcribes the audio as it arrives and translates the sentence while the next one is being spoken, which is the only arrangement that helps somebody watching now.
Not only YouTube
The capture is per tab, so a stream on Twitch, a conference broadcast on the organiser’s own page or a podcast playing in a tab all work by the same mechanism.
What matters is that the sound comes out of a browser tab. A desktop client is outside what a browser extension can reach.

Frequently asked questions
Does it work on ordinary videos too, not just live streams?+
Yes. Anything the tab plays gets translated subtitles.
Do I need to turn YouTube captions on first?+
No. Trippi recognises the audio itself, so it does not depend on the platform’s caption track being present or correct.
Does it work in the YouTube desktop or mobile app?+
No. It is a Chrome extension and works on the stream opened in a browser tab.
Does it translate the video’s existing subtitle track?+
No, and that is the difference worth knowing. Extensions that translate an existing caption track are faster and cheaper on a finished video that already has one. Trippi recognises the audio itself, which is what you need when there is no track yet — a live stream — or when the automatic one is wrong.
Does the streamer or anyone in chat see anything?+
No. The subtitles are drawn in your own tab.
Can I get real-time subtitles on a YouTube live stream?+
Yes — that is the case Trippi is built for. It recognises the audio as it arrives and writes the translated line underneath while the stream runs, so a live broadcast in another language reads in yours in real time, a second or two behind the speech. It does not wait for a finished caption track, which a live stream does not have yet.
