# DubTab

> DubTab is a real-time voice translator with AI dubbing. It adds live subtitles and low-latency dubbed audio to anything that plays sound in the browser or on a Windows or Mac desktop: online courses, livestreams, video calls, and local video files. Nothing is uploaded ahead of time and there is no waiting for a processed file.

DubTab ships as a Chrome extension (works on any browser tab) and a desktop app for Windows 11 and macOS 14.2+ (works with any app that plays audio, including local files, VLC, Zoom, Discord, Spotify, and Steam). The desktop app captures your whole computer or one chosen application; on macOS it asks only for system-audio recording permission, never screen recording and never the microphone. Both share one account and one usage balance. New accounts get a one-time free trial of 15 minutes.

The site is available in 15 languages. Non-English pages live under a locale prefix (for example /es/, /zh-CN/, /ja/); English pages have no prefix.

## Language pairs

One page per language pair, nested under the platform directory. Each exists only in the languages it was written for: an English page is written for English speakers watching with speakers of the target language, and a target-language page (at /es/..., /ru/... or /it/...) is written for those speakers watching English content.

## Help and how-to

Task-based help articles. Translated into all 15 site languages; the URLs below are
the English ones, and each has a locale-prefixed twin (e.g. /es/help/choose-a-voice).

- [Help Center](https://dubtab.com/help): Index of every help article, by category
- [Quick start with the browser extension](https://dubtab.com/help/get-started-extension): Install in Chrome, Edge or Brave, sign in, pick two languages, run a first translation

- [Dub and subtitle a video file from your computer](https://dubtab.com/help/local-files): Open an MP4, MKV, MOV, WebM or MP3 file in the desktop app (1.0.7+); dubbing is prepared a little ahead so it stays in sync, prepared parts replay without using minutes, and the file itself is never uploaded (only the sound of the part being prepared is sent for translation)
- [No captions or translated audio](https://dubtab.com/help/no-captions-or-audio): Two separate failures - nothing appears at all, or captions appear with no dubbed voice
- [Cannot sign in with Google](https://dubtab.com/help/cannot-sign-in): Sign-in goes through Google, so a network that cannot reach Google fails at that step
