The devices, designed as small dongles, can play Internet-streamed audio-visual content on a high-definition television or home audio system. The user can control playback with a mobile device or personal computer through mobile and web apps that can use the Google Cast protocol, or by issuing commands via Google Assistant; later models introduced a navigable user interface and remote control. Content can be mirrored to video models from the Google Chrome web browser on a personal computer or from the screen of some Android devices.
