A virtual agent, also known as a virtual assistant or chatbot, is a computer program or AI-powered software designed to simulate human conversation and assist users with tasks or provide information. These intelligent agents are typically used in customer service, sales, and support roles, and can be accessed through various platforms such as websites, messaging apps, and voice assistants. Virtual agents use natural language processing and machine learning algorithms to understand and respond to user queries, making them an efficient and convenient tool for businesses and individuals alike. With their ability to handle multiple conversations simultaneously and their 24/7 availability, virtual agents are revolutionizing the way we interact with technology and enhancing our daily lives.
