I think the backlash was more against everything being sent to a cloud server where Microsoft can see everything you do.
agreed, the backlash was the cloud + always-on , not the idea itself. thats basically why i only bothered building the local version.
I used the Rewind app on Mac and it was very nice to have the ability to search almost anything you did / saw on the computer. If it's local, opt in, and secure then it's potentially very worth exploring.
thats the point - local, opt-in, nothing leaves the machine. rewind was great but the cloud part scared people off. this runs the whole analysis on-device so the search/chat works without anything being uploaded and it works more as a background service.
