Could you build this?
Partial A launcher app UI can be vibe-coded with tools like Tauri or Electron, but bundling and orchestrating low-level native macOS MLX bindings, memory-efficient local model runtimes, and system-wide global keystroke hooks requires native systems engineering.
What it would actually take: The product requires a native desktop application (Swift/Objective-C or Rust via Tauri) interacting with macOS Accessibility APIs for system-wide text selection and hotkey hooks. The hard part is embedding a high-performance local inference runtime (such as Apple Silicon MLX or llama.cpp native C++ bindings) with graceful memory swapping and process management to ensure the host machine doesn't lag. This needs systems-level C++/Swift expertise and Apple hardware optimization experience.
