InstDub — Your Language. Every Video. von Kyle Leung

Instantly turn YouTube videos into natural speech in your language. Real-time AI translation and dubbing.

InstDub translates YouTube subtitles in real time and generates natural AI voiceover that plays along with the video. Watch foreign-language content in your own language without missing a beat: pick your target language and voice, and InstDub handles the rest.

Sign in once to sync your settings, language preferences, and voice choices across devices. Translation and dubbing run on your InstDub quota or subscription plan.

The extension uses Sentry for crash and error reporting, so we can keep the experience stable and fix issues quickly.
