About

Language should not block a course or a livestream. DubTab overlays real-time AI dubbing and bilingual subtitles on playing audio so you can stay focused. Latency is about half a second. Pick your languages and AI voice, optionally show original and translation together, and duck the source track. The Chrome/Edge extension covers tab audio on Windows, macOS, and Linux; the desktop app covers system or single-app audio on Windows and Mac. Supports 60+ languages. No file uploads. Freemium.

Features

  • Real-time AI dubbing in about 0.5 seconds
  • Live bilingual subtitles (original + translation)
  • 60+ languages and multiple AI voices
  • Chrome/Edge extension and Windows/Mac desktop app
