About DubTab

DubTab is an innovative AI-powered voice translation and dubbing tool designed for seamless multilingual audio consumption across platforms. It operates as a browser extension (Chrome, Edge) and a desktop application (Windows, macOS) that captures audio playing in the browser or any system app, instantly translating and dubbing it into over 50 languages with natural-sounding AI voices. The tool offers real-time subtitles and low-latency voice dubbing with just about a half-second delay, ensuring that learners, stream viewers, and professionals can follow along effortlessly without interrupting audio playback or uploading any files.
