AI Video Subtitle & SRT Generator
The NexVaani AI Video Subtitle and Caption Generator provides creators, video editors, and accessibility teams with a comprehensive in-browser subtitle workstation. By running speech recognition and subtitle alignment locally via Web Speech APIs and HTML5 video decoders, users can transcribe dialogue, adjust cue millisecond timestamps, and generate production-ready SubRip (.srt) and WebVTT (.vtt) caption tracks.
