Google Lens is a visual search tool developed by Google that uses image recognition technology to identify objects, text, and landmarks. Users can take a photo or use their camera to scan items, and the app provides information, suggestions, or related content based on what it sees. This feature is useful for identifying plants, translating text, or finding similar products online. The app is available on both Android and iOS devices, often integrated into the Google Photos app. It enhances everyday experiences by allowing users to interact with the world around them through their smartphone cameras, making information more accessible and engaging.
