This is technically what Microsoft Recall promises to do and no one is happy about it.
Isn’t it also what Apple Intelligence promises to do?
No, IIRC Apple Intelligence does not make such claims. It can keep context within interactions and know about information in some of your silos. Recall has a much bolder feature set in that it wants to beware on everything you see on your screen.
The point of many tasks like this is in the doing. Writing throughout the day what you are working and planning has an effect on your focus and productivity, in and of itself.
Automating this kind of thing is automating your own defeat.
I use Manictime for this. It keeps track of active applications, you can add tags and it can take screenshots at defined intervals. https://www.manictime.com/
Then take that and have it summarized what I did all day on the computer.
