Short answer

An AI chatbot is software that converses with people in natural language, typically using large language models or other machine learning to interpret questions and generate replies. Brands deploy chatbots for customer support, product recommendations, lead qualification and sales. Good implementations connect to accurate business data and hand complex issues to human agents.
