About Subtitle Generator
Create subtitles for YouTube, courses, Reels and Shorts without typing them. Whisper AI listens to your video in the browser and writes timed captions; adjust the maximum line length and two-line layout, fix any word in the editor and download SRT or VTT ready to upload. Can also produce English subtitles from other languages.
