Lol, apple is not logging what your doing, the apple AI just has access to that data directly, no need to copy data from apps you already Control. AppleAI is just a Process that has Access to a lot of data, un fact, any data that any app offer through the API Apple Designes. So that means the AppleAI sees only what the dev of the app want the AppleAI to see. Best case, you can set what you want to give appleAI access to in each app.
I want to ask you, where do you see the difference to Spotlight? Spotlight is also a Process that scanns all your data…
