The chatbot is a virtual robot based on AI (Artificial Intelligence) and is often used to support customer communication services. In addition to text, chatbots can also deliver voice messages. Chatbots carry on conversations in a natural and easy-to-understand language through messaging apps, websites, or mobile apps. With a chatbot, customers get the experience of having a conversation with a robot, but it's like talking directly to a customer service administrator, starting with the language and answering questions customized to look more natural. Also, the service has become faster in terms of answering customer questions.
