Could you build this?
Partial While the UI and menu bar shell are straightforward, running real-time, sub-500ms on-device speech recognition alongside cross-application text injection on macOS requires low-level systems and CoreML integration.
What it would actually take: The stack would involve Swift/Objective-C leveraging CoreML or whisper.cpp for local, zero-network speech transcription. The difficult parts include optimizing inference latency to hit sub-second turnaround without spiking battery usage, robustly managing audio input buffers, and writing reliable text injection fallbacks using macOS Accessibility APIs (AXUIElement) and CGEvent synthesis across diverse native, Electron, and browser targets. This requires native macOS systems programming and on-device ML optimization expertise.
