Translate any browser tab — and hear it, not read it.

What it does

The extension asks the browser for the audio of your active tab, streams it to a real-time translation model, and plays a spoken translation back through your speakers a couple of seconds behind the original. The tab’s own audio is automatically turned down while the translated voice speaks, so the translation sits on top of the original rather than fighting it. Captions for both the source and the translation appear in the popup as the session runs, and accumulate into a transcript you can scroll back through.

It works on whatever the tab is playing: a YouTube video, a Twitch stream, a recorded lecture, a news broadcast, a meeting running in the browser. There is nothing to route and no virtual audio device to install. The extension only ever receives the audio the browser hands it, and only while a session is running — when you stop, it is not listening.

Two ways to run it

The same extension works either on VoxisLive minutes or entirely on your own API key. Own-key mode is covered by the one-time BYOK licence — the same $99.99 unlock as the Windows app, bought once for both — so it is worth being precise about what each mode means.

One key, everywhere

The BYOK licence is a single one-time purchase — $99.99 — and it covers both the Windows app and this extension. Buy it once and you can run on your own API key on your PC and in your browser, with no further per-minute charge from us.

Being plain about what changed: own-key mode in the extension used to be free and ungated, and it is now part of that licence. There is no grandfathering — a key saved in the extension before this change does not unlock it on its own. If you would rather not deal with API keys at all, nothing about account mode changes: it still runs on prepaid minutes and still starts with 15 free ones.

The free tier in the browser

The daily free tier works here too: a new account gets 15 free minutes of the real voice, and after that 10 free minutes every day, the same as the Windows app. What differs is the voice. On Windows and Linux the app ships its own neural voices; a browser extension has nowhere to run those, so it speaks with the voices your browser already has. On Windows that covers 18 of the 79 languages in Chrome and 16 in Edge — the two Edge is missing are Hindi and Indonesian — and the exact list depends on your browser and on the speech voices installed in your operating system. A language with no voice on your machine still translates; it arrives as live captions instead. The extension tells you before you press Start when the language you picked is one of them. The full breakdown is on the languages page. Prefer more spoken languages, or want to translate games and desktop apps? That is the Windows app.

What it will not do

A comparison page that only lists strengths is not worth reading, and neither is a product page.

• It translates the tab, not you. The extension dubs incoming audio. It does not translate your microphone, so it will not speak for you in a call — that is the desktop app’s Meeting mode.
• It only hears the browser. Games, desktop apps and anything outside a tab are out of reach by design; a browser extension can only be handed a browser tab’s audio. The Windows app captures the whole system.
• Some protected streams stay silent. DRM-protected video on certain streaming services will not share its audio with any extension. The desktop app has no such limit, because it captures what the sound card is playing rather than asking the page.
• It is a few seconds behind. A spoken translation cannot be instant — that is the same span a human interpreter needs to hear a thought before rendering it. If you need sub-second text, you want subtitles, not a voice.

Privacy

Audio is captured only while a translation session is running, and recordings are not retained once the translation has been delivered. The extension does not track browsing history, clicks, keystrokes, scrolling or location, and it does not collect health or financial data. In BYOK mode the only thing it sends us is a licence check — when you open the extension, and again when a session starts — carrying your account token and nothing about what you are translating. Your audio and your API key never reach VoxisLive in either mode. The full policy is on the extension privacy page.

Install

Add it from the Chrome Web Store — it runs in Chrome and in Edge. Open it on any tab with Ctrl+Shift+1, pick a target language, and press start. Pricing for account mode is the same prepaid minute balance as the desktop app; see pricing.
