The article explains how to use the iPhone's Magnifier app, which uses Apple's on-device AI and computer vision to detect text, identify objects, describe surroundings, and read printed text aloud in real time. To use it, open the Magnifier app, tap the settings button to add Scene Description to controls, and download required Apple Intelligence models if prompted. Point the camera at tiny writing such as a menu, and the AI analyzes what it sees and begins describing the scene while also magnifying for easy reading. Tapping Scene Description allows the iPhone to read printed text aloud. The feature works best in good lighting and with clearly printed text, and requires a compatible iPhone that supports Apple Intelligence.
