MentraOS overview
What is MentraOS?
MentraOS is the operating system for smart glasses. It is open-source and designed to give users, developers, and manufacturers the best smart glasses experience. Users get apps and freedom to use the AI they want. Developers get an unlocked SDK across glasses devices. Manufacturers get a turnkey OS solution they can integrate while maintaining their brand and customer relationship.
Why do we need MentraOS?
Smart glasses only become mainstream if they feel like glasses first: lightweight, stylish, and able to last all day. Traditional operating systems were not designed for those constraints. MentraOS runs apps on the phone while glasses handle simple input and output, making a powerful software experience possible on hardware people can actually wear.
How does MentraOS work?
To save battery on the glasses, MentraOS apps run on users' phones. Each miniapp runs inside a host app, so multiple apps can work at once, like notifications, translation, and notes. Developers get SDK access to the glasses hardware, including display control, microphone access, and camera commands. Manufacturers can integrate the Mentra Core Engine into their own iPhone or Android app.
How can I start using MentraOS?
If you have supported glasses, you might already be using MentraOS. When the default app says “Powered by Mentra,” MentraOS is inside. If not, check compatibility, download the Mentra app, and connect your glasses to get started.
