Hear any browser tab in your language
Nativizer is a browser extension for live voice translation. One Translate button replaces the original speech with a spoken translation — no subtitles, no extra tabs, no setup.
How it works
Three steps. If you can press a button, you can use it.
Open any video, course, stream, or call in a browser tab and press one button.
Within seconds you hear a live voice translation instead of the original speech. No subtitles to read.
Close the popup — translation continues in the background until you press Stop.
The whole app is one small window
No dashboard to learn. The popup has three states: ready, connecting, and translating.
Two modes: Fast and Max
Pick speed or coverage. Fast is coming soon — everyone starts with Max.
One tab translated, the rest untouched
Translation stays on the tab where you started it. Everything else keeps playing normally.
Starting translation on a second tab stops the first one — only one session runs at a time.
Honest limits, stated plainly
We would rather tell you now than disappoint you later.
Desktop Chromium browsers only (Chrome, Edge, Brave).
One tab at a time — starting a new tab stops the previous one.
Speech is translated; music and sound effects are not.
While the model is thinking you hear silence — the original is not mixed back in.
Protected pages such as the Chrome Web Store cannot be captured.
If the network drops, the missed audio is skipped, not repeated.
Built for Chrome, Edge, and Brave on desktop.
Nothing is recorded or stored — translation happens live.
Usage is counted in seconds. Your first 30 are free.
