AI chatbots are sophisticated software tools that use machine learning algorithms to answer questions from human users in their natural language. These bots are created using pre-programmed scripts, allowing them to detect stored conversation models and respond to them in real time. AI chatbots are used by companies as a form of customer service system, but the best and most comprehensive AI chatbot tools are those that operate as stand-alone software and are not limited in their functionality. AI chatbots provide a more seamless way of getting answers to questions than using search engines.
