About AutoSubs
AutoSubs is a local-first AI subtitle tool. It turns audio or video into timestamped subtitles on your own machine, with no cloud and no data leaving your computer.
It helps video editors and creators add captions. Use it as a standalone app, or connect it to DaVinci Resolve, Adobe Premiere Pro and After Effects. It runs on Mac, Windows and Linux.
Highlights
- Speech to subtitles with several AI models, from fast and lightweight to maximum accuracy
- Automatic speaker labels, so each speaker can have a style
- Transcribe or translate almost any language, processed offline
- Export as SRT or text, or copy to the clipboard
- Send styled subtitles back to Resolve, import caption tracks into Premiere Pro, or create text layers in After Effects
- Command line interface available
