Identify unknown items, locations and key concepts of an image. You'll get different results from the various models that are used to identify your image. This App runs AI ON build in AI hardware on THE PHONE! (so it works in Airplane Mode). It does not use the network or any servers to analyze data and doesn't send the picture to a giant server in the sky like most other apps. Just sayin'. Take a picture with your camera and the machine learning models will identify the key subject in the picture! This is an example of Apple's staggeringly fantastic LOCAL AI on your device!!! Great new Core ML technology. Enjoy!

All on the phone. Never talks to anything. Ever.
