Chatbot

A chatbot is an AI program that communicates with humans through text or voice, simulating natural conversation. The word combines "chat" and "robot." Chatbots are primarily used through websites, apps, social media, and smart speakers. In response to user queries, they automatically reply using pre-defined rules or AI-powered natural language processing (NLP), streamlining inquiry handling and customer guidance. In recent years, advanced chatbots using generative AI have emerged, capable of conversations virtually indistinguishable from those with a human. The main types of chatbots include: • Rule-based chatbots: Respond based on predefined flows or keywords (e.g., FAQ handling) • AI-based chatbots (NLP-based): Analyze user input and reply flexibly (e.g., ChatGPT) Use cases span customer support, reservation handling, internal help desks, product recommendations, and educational support — and adoption is growing across industries and company sizes. The benefits of 24/7 availability, cost reduction, and improved user experience are driving increasing business adoption. Integration with generative AI has evolved chatbots into advanced conversational interfaces that go far beyond traditional chatbots, and their expansion into even more diverse fields is expected going forward.
