Build me a macOS app that works system wide and suggests short autocomplete continuations in any text field, kind of like ghost text that appears at the cursor and can be accepted with Tab.

It should run locally on the Mac, use an on device language model, and feel lightweight enough to live in the menu bar. I want it to watch the currently focused text box across apps, figure out the surrounding text, and offer a small inline completion without sending anything to the cloud.

Please make the first run experience simple, with clear onboarding and the permissions needed for accessibility and text input. Also include a basic settings screen so I can turn the feature on and off and manage app specific behavior if needed.

If you need to look up current macOS or Xcode docs while building it, go ahead.
