Impressive latency numbers! I’ll definitely try replacing super whisper with this.
Key features: - ~300ms latency with Deepgram WebSocket streaming - Local mode with MLX/Lightning on Apple Silicon (M1/M2/M3) - Context-aware LLM refinement (detects email, chat, code) - Just fixed it for macOS 26 (Tahoe) this week
Technical stack: Python, PyObjC for native macOS UI, MLX for local inference.
The tricky part was getting <500ms end-to-end latency. We stream audio over WebSocket while recording, so results appear immediately when you stop.
