Chatbot
Core ConceptsA software application that simulates conversation with users, ranging from simple rule-based systems to sophisticated AI-powered assistants like ChatGPT.
A chatbot is any software designed to converse with humans through text or voice. The term covers a huge range — from the annoying 'How can I help you?' popup on websites (usually rule-based) to ChatGPT and Claude (powered by large language models).
Modern AI chatbots are fundamentally different from old-school chatbots. Traditional chatbots followed decision trees: if the user says X, respond with Y. LLM-powered chatbots actually understand context, generate novel responses, and can handle conversations they were never explicitly programmed for.
The chatbot market divides into consumer chatbots (ChatGPT, Claude, Gemini), customer service chatbots (Intercom Fin, Tidio), and specialized chatbots (Character.ai for roleplay, Replika for companionship).
Real-World Example
The line between a chatbot and an assistant is mostly marketing. What matters is whether it keeps context across turns and whether it can act on anything outside the conversation.
