Windows

Desktop app

Everything your computer plays — browser tabs included — or just the one app you pick. Video files on your computer, like downloaded lessons, open right in the app, with the dub prepared a little ahead so it keeps pace.

The same app, on your Mac. Everything your computer plays — browser tabs included — or just the one app you pick. macOS asks once to allow recording system audio; it never asks for screen recording or your microphone.

No microphoneDubTab can't use your microphone at all. It only hears what your computer is playing, never you.

Before you install

I'm on Windows 10 — can I use the desktop app?

Sorry, no — it only works on Windows 11. Windows 10 doesn't have the audio feature the app relies on, so there's no way around it. The extension works on any computer though, and it covers every course that plays in your browser.

Do I have to choose? Can I use both?

Use both. They share one account and the same hours, so nothing is wasted either way. Use the extension for courses that play in your browser; for lessons you've downloaded, open the file in the app — the extension can't open files on your computer.

How do I install DubTab on Mac?

Requires macOS 14.2 or later. Choose Apple Silicon or Intel to match your Mac, open the DMG, and drag DubTab to Applications. Allow system audio recording when prompted on first use.

How does the app update itself?

By itself, in the background — you don't have to do anything. Updates are small and quick. If you'd rather check for one yourself, there's a button in Settings.

Still not sure which one?

Start with the extension — it's free to install and takes one click. If you add the app later, both still use the same pool of hours.
