Hey Product Hunt! 👋 I built Voxylio because the best content on the web — courses, conferences, documentaries — is in English, and reading subtitles for an hour is exhausting. I wanted to press play and just… listen, in my language. So that's what Voxylio does: it reads the video's subtitles as they come, rebuilds complete sentences, translates them, and speaks them over the video, synced with playback. The original audio ducks under the voice automatically. A few things I'm proud of: 🌍 65+ dubbing languages, with automatic source-language detection ⚡ On YouTube and Udemy, the full caption track loads upfront — the voice never lags behind 🔒 The free translation runs locally in your browser 🎧 It even detects when YouTube is already auto-dubbing a video, so you never get two voices 📖 The source code is public (FSL license) It works on streaming platforms (Netflix, Prime Video, Disney+, Twitch…), course platforms (Udemy, Coursera, LinkedIn Learning…), and any site whose player exposes subtitles. Available today on Chrome and Edge — Firefox and Safari are in review. I'd love your feedback: which site should Voxylio support next? I'll be here all day answering everything. 🎙️
