The exact wording, which, again, is in the article you didn't bother to read before posting, is "Quickly find things you've seen with Recall. Recall helps you find things you've seen on your PC when you allow Windows to save snapshots of your screen every few seconds".
Seriously, I don't even like the feature. I will absolutely turn it off, just like I did Timeline, and I expect it'll be gone in the next version, just like Timeline was.
But I did look at the stupid article before posting. So there's that.
