Chatbots use artificial intelligence to interact with users through natural language processing (NLP) and machine learning algorithms. These technologies enable chatbots to understand and interpret user inputs, allowing for engaging conversations. By analyzing user queries, chatbots can provide relevant responses, assist with information retrieval, and perform tasks like booking appointments or retrieving account details. Additionally, chatbots continuously learn from interactions, improving their responses over time. This creates a dynamic experience that enhances customer support and engagement across various platforms and applications.
