About this extension
dubly.me adds real-time AI dubbing and translated subtitles to online video - so you can watch YouTube, Udemy, Coursera, Vimeo and any other site with an HTML5 video player in your own language.
Found the perfect video, lecture or course... in a language you don't speak? Install dubly.me, open the video, pick your language - and hear it dubbed, read it in subtitles, or both. No uploading, no downloading, no editing. It just works, right in your browser.
HOW IT WORKS
1. Add dubly.me to Firefox
2. Open a video on any site with an HTML5 player
3. Pick your language and a mode: Dubbed voice, Subtitles or Both - the first minutes play instantly, the rest streams in the background
TWO WAYS TO WATCH
- Dubbed voice: natural AI speech over the video, made for lectures, tutorials and courses
- Subtitles: the original sound stays and the translation appears on screen - no voice is generated, made for films and series
- Both: listen and read along, handy for language learners
WHAT YOU GET
- Real-time AI dubbing with 322 natural neural voices
- Translated subtitles in all 115 languages - European, Asian, Middle Eastern and more, including Chinese (Simplified, Traditional and Cantonese)
- Context-aware AI translation
- First minutes play instantly - no waiting for the full video
DEDICATED SUPPORT FOR 9 PLATFORMS
YouTube, Udemy, Coursera, Vimeo, edX, TED, Loom, Netflix and Rumble get controls built into their own player. Every other site with an HTML5 video player works through a generic overlay.
MADE IN THE EU
Hosted in the EU. GDPR compliant. Your video and audio are never stored.
PERFECT FOR

FREE AND BASIC
- Free: 30 minutes a day with a free account (10 minutes a day without one) - no credit card needed
