Where it works
Real-time translation for any tab with sound
YouTube™ and other video sites
Live streams, as they happen
Online courses and webinars
Web meetings: you hear the others
Chrome’s own pages can’t be captured, and some DRM-protected players give no sound. Other people’s voices in a tab go to Google too: make sure you’re allowed to.
How it works
Translate any video in three steps
- 1
Get a Gemini API key in Google AI Studio and turn on billing.
- 2
Paste it into DubBuddy: it stays encrypted on your computer.
- 3
Click the DubBuddy icon on a video, then press Start.

Each line as it’s said, with its translation under it if you like.
What it costs
DubBuddy charges nothing. Google bills your own key, by the minute.
At Google’s own prices, which it sets and may change.
- Without billing, a key runs on Google’s free tier, within its limits, and Google may use the audio to improve its products, except in the EEA, Switzerland and the UK. With billing on, it does not.
- A muted dub is still billed; silence is not sent.

Privacy
The tab’s audio goes to Google. Nothing comes to us.
No DubBuddy server
The audio, and any lines to translate, go straight to Google, only while a session you started runs.
No code in your pages
DubBuddy reads nothing from the page; Chrome tells it the tab’s title and address.
History on this device
Each session’s words stay here, never the audio. Off in Settings.

About 3 seconds, and the first words arrive about 5 seconds after Start. The original is lowered only while the dub plays, so you still hear the speaker underneath. Machine translation can mishear names and terms.
You pick the language; Google’s model picks the accent and the variety of the language the dub speaks, and DubBuddy cannot change them. An Arabic dub, for example, can come out in colloquial Egyptian Arabic rather than Modern Standard Arabic.
Those parts are not dubbed: you hear the speaker. The audio is still sent and billed, so on a tab wholly in your language the panel says so (“Already in English”), and the session stops by itself after 20 minutes of sound with no dub.
YouTube dubs some recorded videos itself, in advance and free, and its dub replaces the voice. DubBuddy dubs whatever the tab plays, live streams included, into any of 78 languages, keeps the voice underneath and runs only when you press Start; Google bills your key. See how the two compare.
Chrome 116 or later on a computer, and a Gemini API key from Google AI Studio, which Google bills. Google’s Gemini API terms apply to the key (18+), and the Gemini API is not available in every region. DubBuddy does not run on phones.
Yes: Microsoft Edge, Opera, Vivaldi and Brave (tested in October 2026), installed from the Chrome Web Store. Not Firefox or Safari: they don’t let an extension capture a tab’s audio.
Its panel and welcome page are in the 15 languages of this site. It follows your browser’s language, and you can change it at the top of Settings.
That is how Chrome words the permission to capture a tab’s audio. DubBuddy captures only the audio of the tab you start it on, never video, and runs no code in the pages you visit. The privacy policy says exactly what it sends, to whom, and what it keeps.
Watch the stream. Listen in your language.
Add DubBuddy to Chrome, paste a Gemini API key, and click the icon on a video.
