Meet Kai: a smart gadget that stays behind your ear on your glasses and makes them smart. It allows you to use voice commands to make call, searches, or even summon an Uber. The device gives you access to your calendar, notes, news, notifications, navigation, and more.
You can create custom profiles for home, work, and other locations. Kai doesn’t take a lot of space and stays out of your field of view. More info is available here.
