What is a Chatbot vs an AI Agent?
A chatbot is an AI system designed for conversation — it receives messages and generates responses within a single interaction loop. An AI agent is an autonomous system that can plan, use tools, take actions in the real world, and pursue multi-step goals with minimal human intervention. The key distinction is autonomy and action scope.
Why It Matters
The terms "chatbot" and "AI agent" are often conflated, but they represent fundamentally different capabilities. Understanding the distinction helps businesses set realistic expectations: a chatbot answers questions; an agent books meetings, writes code, queries databases, and orchestrates workflows. The industry is moving rapidly from chatbots to agents, and the difference matters for architecture, safety, and cost.
How It Works
Chatbot characteristics:
- Reactive: responds to user messages
- Stateless or limited context: each conversation is relatively independent
- Single modality: typically text in, text out
- No tool use: generates text responses only
- Human-in-the-loop: user drives every interaction step
- Examples: basic customer support bots, FAQ bots, early ChatGPT
AI Agent characteristics:
- Proactive: can initiate actions and pursue goals
- Stateful: maintains context across long task sequences
