Microsoft’s Recall on the new Copilot+ PCs is quite impressive:

"Now with Recall, you can access virtually what you have seen or done on your PC in a way that feels like having photographic memory."

There are obvious trade-offs using this if someone gets access to your computer, but I’d be comfortable with it if there are enough settings. For example, maybe I only want the recall to go back one week, not months.
