FlashCaption troch MG Media LLC

Real-time captions and live translation for any video or livestream, right inside Firefox.

Ever watched a stream, a match, or a video in a language you don't speak and missed half of it? FlashCaption listens to whatever is playing in your tab and puts AI subtitles on screen as people speak, translated into the language you actually read. Whatever the language, you stay in sync.

Start with a 7-day free trial. Full access from minute one, and you can cancel any time before it ends. Turn it on and captions appear live. No setup, no uploads, no switching tabs.
