Real-time Video Translator & Dubbing - DubTab

DubTab helps you understand any video in your browser by dubbing it in real time. When you’re watching YouTube, online courses, K-pop livestreams, product demos, webinars, or any site with spoken audio, DubTab: - translates what you’re hearing as it happens, - shows live translated subtitles on screen, and - plays a natural AI voice speaking the translation (real-time dubbing). If you’ve ever thought “I wish this video had a voiceover in my language” — that’s exactly what DubTab is built for. 🎧 What DubTab is best at - Real-time AI dubbing (the main feature) DubTab turns speech into translated speech with low latency, so you can keep watching without constantly staring at subtitles. - Live translated subtitles Subtitles appear in real time, so you can follow every sentence as it’s spoken. - Bilingual subtitles (when you want both) Show original + translation together — great for learning or quick accuracy checks. - Choose a voice you like Pick from multiple voices so the dub sounds clear and comfortable to listen to. - Save your dubbing Save the generated dubbing so you can listen to the translated content again later—useful for courses, tutorials, talks, and other content you want to revisit. - Works on any tab that’s playing audio Great for YouTube, video platforms, courses, K-pop livestreams, webinars, and more. 🧠 Understand more with AI - AI Summary Turn long videos, lessons, and livestreams into clear summaries and key takeaways, so you can quickly review what you watched. - AI Mind Map Generate a visual mind map from the transcript to organize the main topics, subtopics, and key ideas—especially useful for reviewing long lessons and complex explanations. - Ask AI about what you watched Ask questions based on the transcript — clarify confusing explanations, review important concepts, or find information without searching through the whole video again. ✨ Use cases - Keep up with fast-paced tutorials, courses, and tech talks without missing details - Language learning with bilingual subtitles + spoken translation - Teams who consume international content (training, demos, talks) - Watch YouTube videos in other languages hands-free (listen instead of reading) - Follow K-pop livestreams and understand what’s happening in real time 🪄 How it works 1) Install DubTab 2) Play a video/audio in your browser 3) Select your Target Language (and source if needed) 4) DubTab shows live translated subtitles and starts dubbing 5) Listen to the translated voice in real time 6) Generate a summary and mind map, or ask AI questions about what you watched 🔒 Privacy & support DubTab is built with privacy in mind and designed to support GDPR principles.
