AI Video Dub

AI Voice Dubbing (NEW): Powered by Microsoft Neural TTS — over 400 natural-sounding voices across 70+ languages. Each language has multiple voice options (male/female). Audio is pre-generated before playback starts for seamless, synchronized dubbing with no delays.

Video to Text: Get the full transcript of any YouTube video with timecodes. Click any line to jump to that exact moment — perfect for finding key points, quotes, or re-watching specific scenes. Translate the entire transcript into any of 50+ supported languages. Copy with one click or download as SRT subtitle file for use in video players or editors.

Subtitle History: A draggable, resizable panel displays every subtitle that was voiced during your session, so you can scroll back through the entire conversation. Copy the whole history with one click for note-taking, language learning, or documentation.

SRT Subtitle Download (NEW): Download translated subtitles as standard .srt files. Compatible with all major video players (VLC, MPV) and video editors (Premiere, DaVinci). Perfect for content creators who want to add subtitles to their own videos.

Customizable Playback:

• Adjust voice volume and original audio volume independently
• Change speech rate from 0.5x to 1.5x
• Select from multiple AI voices per language
• Show or hide translated and original subtitles
