What can Google Lens do?

Aside from the scenarios described above, Google Lens offers the following features:

  • Translate: You can point your phone at text and, with Google Translate plugging in, live translate text in front of your very eyes. Magic.
  • Smart Text Selection: You can point your phone's camera at text, then highlight that text within Google Lens, and copy it to use on your phone. So, for instance, imagine pointing your phone at a Wi-Fi password and being able to copy/paste it into a Wi-Fi login screen.
  • Smart Text search: When you highlight text in Google Lens, you can also search that text with Google Assistant. This is handy if you need to look up a definition of word, for instance.
  • Shopping: If you see a dress you like while shopping, Google Lens can identify that piece and similar articles of clothing. This works forhousehold decor and more, too, via relevant reviews and shopping options.
  • Search around you: If you point your camera around you, Google Lens will detect and identify your surroundings. For us that meant IDing the kinds of plants, breeds of pet cats, and highlighting reviews of DVDs from our entertainment stand.
