Hi Product Hunt! I built DubFlow because I kept finding great lectures and interviews on YouTube in languages I don't speak, and reading auto-translated subtitles while watching is exhausting. DubFlow is a Chrome extension that adds one button to the YouTube player. Pick a language, press Dub, and the video keeps playing with a translated AI voice over it, timed to the captions. The original track stays audible at about five percent so music and laughter don't vanish, and stopping the dub brings it straight back. Nine languages, preset female and male voices, no voice cloning, and a floating subtitle overlay if you want to read along. The free plan covers three videos a day, up to three hours each, with no card. I'd love to hear which languages and channels you'd use it on, and what's missing.
