A Conversational Agent is a computer program designed to simulate human-like conversations. These agents can understand and respond to user inputs, often using natural language processing (NLP) techniques. They are commonly found in applications like chatbots and virtual assistants, helping users with tasks or providing information. Conversational agents can be used in various settings, including customer service, education, and entertainment. They can operate through text or voice interfaces, making them accessible on platforms such as websites, mobile apps, and smart devices like Amazon Alexa or Google Assistant.
