Google is developing two types of smart glasses: a lightweight, screen-free model in collaboration with fashion brands and a display-equipped version with hardware partners like Samsung and Magic Leap. A companion app for the glasses has been identified, featuring a pairing process and settings for power management and camera functionality. The app includes AI capabilities such as 'Conversation detection' to silence notifications during conversations, and it ensures that all recorded data remains private to the user. Additional features in the app allow for display adjustments and an "audio only mode."
