Visual Look Up is Apple's version of Google Lens that's built right into the Photos app on iOS. The feature can recognize objects from photos you've taken or saved on your iPhone, and can be used to search for the exact type of object or the specific category it belongs to.
How to Fix Visual Lookup Not Working on iPhone/iPad
If you can't use the Visual Lookup option on your iPhone or you don't have access to it in the Photos app, the following post will show you a way to make it work anyway.
The Photos app on iOS has a Visual Look Up feature that uses machine learning to identify objects in photos you've saved and give you more information about them. The feature can be used to recognize objects and find the exact type or category they fall into.
For example, when you call Visual Look Up on a photo of a dog, it will not only show you that it is a dog, but it will also attempt to identify the dog's breed and provide more information about the dog. You can use the feature to pin pets, landmarks, plants, and artwork.
