Core Chat

Core Chat is a client for the Matrix protocol, based on the Element X app.

The Matrix protocol is a decentralized approach to modern messaging, allowing you to select a server provider of your choice (or even self-host your own server), enabling you to communicate with end-to-end encryption, shared message history across multiple devices, voice and video calls, and more.

Core Chat is based on the open-source Element X project: https://github.com/element-hq/element-x-android
