Karaoke Captions is a browser editor for animated, word-by-word video captions. Add a video, generate a transcript on your device or import SRT, review the words and timing, choose a style, and export MP4, SRT or VTT.

The library has 100+ caption styles and continues to expand. Classic and Lyrics offer unlimited watermark-free exports without an account. Pro styles and creative tools can be tried with a small export watermark; Pro removes it.

Whisper runs locally through Transformers.js using WebGPU or WebAssembly. Video transcription and rendering stay on your device. The app and speech model need an initial download; after loading, the local workflow can work offline. Desktop Chrome or Edge is recommended for MP4 export.

Built for creators making Reels, Shorts, TikToks, tutorials and dialogue clips. Review automatic transcripts before publishing.
