How It Works

Professional captioning in four simple steps, all powered by secure, local AI technology.

Select your video or audio file. We support all major formats including MP4, MOV, MP3, and WAV.

Files are never uploaded to our servers. They are loaded directly into your browser's memory for maximum privacy and speed.

Our local AI model automatically detects speech and generates accurate captions with word-level timing.

Edit text, fix timings, and apply beautiful styling templates to match your brand.

Choose from hundreds of styles or build your own with advanced typography controls, animations, and color palettes.

Burn the captions directly into your video or export them as standard SRT/VTT files.

Hardware-accelerated encoding ensures your final video renders quickly while maintaining pristine visual quality.
