Google Lens seems to be a item to have. It is available through other Google apps, such as Google Assistant, Google Photos, some camera apps, Android devices, in Google Photos on iOS and in the Google app on iOS. The apps it is on will show it as four rounded corners with a dot in the middle. So let’s see exactly what it does.
Say you are out taking a walk and see a plant you and you don’t know what it is. If you take a picture of it, it will find it and bring up web results so you can see it. Same with animals. On iOS, if I open the Google app, click on the lens icon in the search bar, I can see it has accessed my camera (I had given previous permissions) and some dots appear. If I click on one of the dots, it will find the item I have clicked on.
If you hover over text that is in another language, you can touch the Google Translate button and it will translate to English for you.
