Google Duo is a video calling app that is designed to be simple and reliable. It works on iPhones, Android phones, and Chromebooks. Chromebooks are laptops that run on the Chrome operating system.
Google Duo is not available on Chromebooks because it does not support the WebRTC (Web Real-Time Communication) standard that is required for video calling. WebRTC is a browser-based technology that is used for real-time communication, such as video calls.
Chromebooks use the Android version of Google Duo, which does not support WebRTC. This means that users cannot make video calls on Chromebooks.
There are a few alternatives to Google Duo that work on Chromebooks. One option is Skype, which supports WebRTC. Another option is Hangouts, which is also made by Google.
