Could you build this?
No A system-wide desktop assistant that watches the screen, indexes continuous meeting/conversation history, and injects context-aware text into arbitrary native applications requires intricate OS-level hook architecture and privacy-preserving background processing.
What it would actually take: Built with Swift/Objective-C/C++ or Rust leveraging macOS Accessibility APIs, CGWindowList screen capture, CoreAudio capture, and local vector storage. Hard parts include reliable context extraction across disparate native/web applications, low-latency cross-application cursor injection, and managing continuous screen/audio OCR without battery drain or privacy leaks. Requires deep native systems engineering experience.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
