Could you build this?
Partial While wrapping a local SLM is straightforward, building an OS-wide accessibility-based injection system on macOS with sub-second ghost text overlay is technically challenging.
What it would actually take: A native Swift/Objective-C app using the macOS Accessibility API (AXUIElement) to track active text inputs, caret positions, and keystrokes across arbitrary third-party apps. It requires running a quantized local model (via MLX or llama.cpp) tuned for next-token autocomplete with strict latency constraints (<50ms), and custom Cocoa overlay windows to render inline completion ghost text.
