InstDub — Your Language. Every Video. EN

InstDub instantly translates YouTube videos into your language with real-time subtitles and natural AI voiceover. Never pause to read or translate again — just watch, listen, and understand.

Real-time subtitle translation: As the video plays, subtitles are translated into your preferred language in real time, with support for early playback so you never miss a beat.

Natural AI voiceover: Choose from a wide range of natural-sounding AI voices and have the video dubbed in your language while you watch. The original audio is automatically lowered while the dubbed voice plays, so you always hear the translation clearly.

Seamless YouTube integration: Works directly inside the YouTube player on desktop and YouTube's mobile/TV web interfaces. No copy-paste, no switching tabs — the translation appears right where you need it.

Wide language support: Translate and dub videos across dozens of source and target languages, with voice catalogs tuned for both domestic and international markets.

Your settings, remembered: The extension stores your selected language, voice preference, and region securely, so your setup is ready the moment you open a video.

Privacy-conscious: Your account data is stored locally in your browser and used only to authenticate requests to the InstDub API. No browsing history or personal data is collected or sold.
