Could you build this?

Partial A basic macOS menu/notch UI with local LLM bindings via llama.cpp or Ollama is achievable, but real-time system audio transcription, proactive screen contextual recall, and low-latency notch integrations require native Apple Silicon and macOS API engineering.

What it would actually take: The app requires Swift/SwiftUI with native AppKit hooks for custom borderless floating NSWindows over the notch area. The local AI pipeline requires Apple's Metal Performance Shaders (MPSGraph) or CoreML/MLX running quantized local models, ScreenCaptureKit for contextual optical capture, and low-level CoreAudio taps feeding whisper.cpp for real-time meeting transcription without audio loopback lag.
