Could you build this?
Partial While wrapping whisper.cpp or Apple Speech into an electron/macOS menu bar app is straightforward, achieving ultra-low-latency real-time on-device streaming dictation and OS-level keyboard injection requires specialized native performance tuning.
What it would actually take: The app likely relies on Swift/Objective-C with Apple Silicon optimizations (CoreML, Metal, or whisper.cpp via Accelerate framework) and macOS Accessibility APIs for virtual keypress injection. The hard part is tuning streaming ASR to achieve near-instant latency without high CPU/RAM overhead or audio buffer drops. It requires audio engineering expertise, low-level macOS system programming, and model quantization tuning.
