Could you build this?
Partial While loading a local small language model is straightforward, intercepting cursor positions and rendering system-wide ghost text reliably across arbitrary macOS apps requires tricky macOS Accessibility and Input Method Kit APIs.
What it would actually take: A native macOS app in Swift/Objective-C using macOS Accessibility APIs (AXUIElement) or an Input Method Kit (IMK) engine to hook into active text fields across arbitrary third-party apps, compute caret bounds, and overlay transparent floating ghost text windows. The local inference engine can be powered by llama.cpp or Apple MLX running a quantized lightweight model (1B-3B parameters). The primary challenge lies in handling accessibility quirks, non-standard UI toolkits (Chromium, Electron, Flutter), and low-latency input event interception without lagging the OS.
