AutoSubs
Local-first AI subtitles. No cloud, no subscription, no data leaving your machine.
Use it as a standalone app, or connect to DaVinci Resolve, Adobe Premiere Pro, and After Effects.
- 🎙️ Speech to Subtitles: Turns audio or video into accurate, timestamped subtitles. Pick from several AI models, from fast and lightweight to maximum accuracy.
- 👥 Speaker Labels: Automatically detects who is speaking and labels each speaker, so you can give each person their own style.
- 🌍 1,000+ Languages: Transcribe or translate almost any language, all processed on your own machine.
- 💻 Mac, Windows & Linux: Works on Apple Silicon and Intel Macs, Windows, and Linux. Everything runs offline.

Supported Models
AutoSubs ships with several local transcription model families. All run fully on-device — nothing is sent to the cloud. Models are downloaded on demand from the in-app Model Manager.
Accuracy is a relative 1–4 rating within AutoSubs (higher is better). Sizes and RAM figures are approximate.
Whisper
OpenAI's Whisper, via whisper-rs (GGML). Each size is available in a multilingual variant and an .en English-only variant (the .en models are slightly more accurate on English audio).
