Subtitle Generator
AutoSubs generates subtitles locally and can run on its own or integrate with DaVinci Resolve, Premiere Pro, and After Effects.
About Subtitle Generator
AutoSubs transcribes audio or video and produces subtitles on the user's own computer. It can run on its own, or it can be connected to DaVinci Resolve, Premiere Pro, and After Effects, where the generated text is placed on a timeline, caption track, or text layer. The homepage says transcription runs on the device, with no upload, account, or telemetry. It also says footage under NDA stays on the drive it came from. The homepage describes the software as free, but the directory has no verified pricing. Licensing is described inconsistently: the homepage calls it open source under the MIT license, while the directory record lists it as not open source.
The software offers several speech recognition model families, including Whisper, Parakeet, and Canary. Models are downloaded on demand, and their sizes range from about 40 MB to 3.7 GB. Language coverage depends on the model. The homepage's speed figure of 30 times faster than real time, with no GPU required, applies to specific models tested on an Apple M3 MacBook Pro. Installers are listed for macOS, Windows, and Linux.
