Chatbot: Definition & Explanation
A chatbot is a program that engages in automated conversations with humans through text or voice. While traditional rule-based chatbots could only respond according to pre-defined scripts, the advent of LLMs has enabled natural conversations, complex question handling, and contextual understanding. Chatbots are widely used for customer support, FAQ responses, appointment booking, and internal help desks. In addition to general-purpose AI chatbots like ChatGPT, Claude, and Gemini, platforms like Botpress, Voiceflow, and Dify enable businesses to build custom chatbots. When combined with RAG technology, chatbots can provide accurate answers grounded in internal documents and knowledge bases. Recently, chatbots are evolving into AI agents capable of not just conversation but actual task execution.
