Features & Capabilities

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.

Is InstDub — Your Language. Every Video. Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

InstDub — Your Language. Every Video. requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
