Google came out with a new version of Google Lens in beta, the company announced at its annual developer conference on Tuesday. If you have one of the ten additional Android devices that are getting Google Lens inside their native camera apps, you’ll be able to access the feature simply by going into your camera and seeing the icon on the bottom right.

Tapping on the icon activates the Google Lens feature and you’ll be able to point your smartphone camera at objects and different sights to identify more information about them. Google Lens is also getting a real-time finder that will analyze what your camera sees even before you tap on the display. The tool will process the pixels through machine learning to provide more details and also provide relevant search tags.
