Replacing the background
Express your personality (or make that laundry behind you disappear) with beautiful backgrounds or your own photos: thanks to cutting-edge segmentation technology, you'll always look your best.
More control over web videos
When Safari detects a video on a page, the video viewer helps you bring it to the foreground while still leaving you full access to system controls.
Schedule sending messages
It's the middle of the night and you have to write something very important that you're afraid of forgetting? Now you can write a message and postpone its sending, making it start at the time you want.
Voice Isolation on AirPods Pro
Perfectly clear sound during calls, even in windy or noisy areas. This is thanks to advanced computational audio.
