Offline subtitle generator

Offline subtitle generator for Windows, Mac soon

Short answer: to generate subtitles offline, use a tool that runs the speech model on your own computer. Offline Captions does that and gives you two outputs at once: an SRT subtitle file and a video with animated captions burned in. The free web version does the same in your browser for clips up to 5 minutes and also exports VTT and plain text.
