Google Assistant does a lot of things. This invisible artificial intelligence residing (partly) inside our devices can answer all kinds of questions, control our homes, help us plan our day, play our favorite music, and, with the addition of features like What's on my screen and Google Lens, glean more from what we're looking at and provide contextual answers. What you may not be aware of, and something I recently discovered (though it isn't very new), is that Assistant can read your screen even when you don't explicitly ask it what's on your screen. That has the potential to be very handy, but also extremely creepy if you didn't know it was possible.
