Like that, but filtered through an AI.

Features: questions like "Hey, where's that file I worked on last week", "What was that recipe I found the other day" or "hey can you pull up a copy of this document from 3 days ago so I can compare them" all work. Its nice to be able to just do that, and you can apply all the normal AI editing things to them, too. They're all available.

Downside: a black box AI system the user doesn't have full control over has the right to record literally everything you do on your computer. They promise its local, for now, but not only is Microsoft not trustworthy in that regard, even if they're honest we don't know if or when they'll change that policy. I would not be surprised if the next step was "A small amount of none identifiable information is transmitted to our servers" snuck in, and they used that permission to have Microsoft Recall answer queries for advertisers directly, technically without ever identifying you. Advertisers could directly ask your own computer for all the info they'll ever need.

And, yes, Mac still has Time Machine. Linux has its own version, too. Both are very handy and I've used them each personally. In my personal opinion, a basic search with time machine does enough of Microsoft recall's job that I'm not going near it, but honestly at least you're getting functionality out of them selling your data, so it could be worse.

Time Machine (which is an excellent feature on macOS btw and isn't advertised nearly enough by Apple), but Recall sounds more like an automatic clipboard history that saves more than just text and copied images, not something that lets you roll back to a previous state.
