Theoretically, if you're forgetful, ADHD, or multitask like crazy, you can use Recall as a memory supplement. Whatever you were working on, your computer remembers so that you can view it later. Additionally, it runs everything you do through an AI so that the search capabilities work "really well" (we hope!). (edit: originally I thought Recall also suggested what you wanted to do next, I was wrong, nevermind on that) That's supposedly going to help you work more efficiently.

Of course this comes with huge security and legal risks, plus privacy concerns since Microsoft's software is now watching everything you do on your computer.

If they had forgone the AI bit, released it as an open-source project, made it an opt-in application that you have to intentionally install, and implemented some actually good security, Recall might have actually been quite handy. The concept has merit, it's just the implementation is horribly flawed and a massive liability. They might still be able to redeem it somewhat if they open-source it and make the security better (i.e., *actually* encrypt the database and require the user to provide their password to decrypt it before viewing it), but I don't find that too likely to happen.
