An AI agent is an intelligent system that can think, learn, and make decisions automatically. It analyzes data, understands user input, and takes actions to achieve specific goals. AI agents can work 24/7, improve over time, and help users complete tasks faster and more efficiently. They are used in many areas such as customer support, gaming, finance, and automation.
