About Karaoke Captions
Private word-by-word video captions, processed in your browser
Karaoke Captions is a browser-based editor for animated, word-by-word video captions. It is built for TikTok, Instagram Reels, YouTube Shorts, podcast clips and tutorials. Drop in a clip, generate a transcript, correct text and timing, choose a look, and export an MP4 with captions burned in. SRT and VTT exports are also available. Speech recognition and video rendering run on the device, so source footage is not uploaded. After the app and speech model have loaded, captioning can continue offline. The library has 100+ caption styles and continues to expand. Classic and Lyrics are free, with unlimited watermark-free exports and no account. Every Pro style can be tried before buying; free Pro-style exports have a small watermark, and Pro removes it. Pro also adds auto emoji, smart highlights and filler-word cleanup. Desktop Chrome or Edge is recommended for MP4 export. Built with React, TypeScript, Remotion Player, Whisper, Transformers.js, WebGPU/WebAssembly and WebCodecs.
