I don't know about deep level impressive but I'm finding the new Google Lens thing built recently into Chrome pretty cool and useful. You click it and highlight part of the page and then it figures what the image is or ocr's text in it and optional translates or searches it. I use it multiple times per day. Also just being able to do that was a bit sci-fi 15 years ago.
