Web chat is a real-time communication between two or more people over the internet. It involves typing messages back and forth in a chat window, similar to sending instant messages or emails. The difference with web chat is that it typically takes place on a website where customers can interact with customer service representatives or get answers to their questions without having to pick up the phone or send an email. Web chats are often used by businesses as a way of providing better customer support and improving the overall user experience.
