A chatbot interacts with users through a conversational interface, simulating human-like dialogue. Users can engage with chatbots via text or voice, and the bot employs natural language processing (NLP) to understand and respond to user queries appropriately. The interaction typically follows a predefined script or utilizes machine learning algorithms to adapt responses based on user behavior and context. This allows chatbots to provide support, answer questions, and even complete transactions, often enhancing customer service efforts for businesses.
