The Angular UIKit components work together to deliver a complete chat experience. The sections below map each core feature to the components that implement it, so you can quickly find the right building block for any capability. ## Instant Messaging Real-time text messaging is at the heart of CometChat. Users can send and receive instant messages, enabling quick and efficient communication in both one-on-one and group conversations.
