Hush – local push-to-talk dictation for macOS, no cloud, pastes at cursor (github.com)

Interesting that you use Whisper for local transcription. We built something comparable in speech-swift (which I maintain), focusing on on-device ASR with Qwen3-ASR, which supports 52 languages and achieves an RTF of 0.06 on Apple Silicon. The tradeoff is full native Swift async integration. https://github.com/soniqo/speech-swift
