It's hard to think of a more self-explanatory feature than Circle to Search: it does exactly what it sounds like it does. You circle something on your phone screen, tap a button, and voila! A page full of Google search results telling you about the thing you circled. Easy, right?
Is it a radical new way to search for things on the internet? No, but it looks legitimately handy. Sometimes, the administrative overhead of taking a screenshot, closing an app, opening another app, and selecting the screenshot is just too much to bear. Circle to Search cuts out the grunt work, and it's one of those features that just makes sense, like your phone should have been capable of it all along.
