What's the difference between an AI chatbot and an AI agent

What Defines a Chatbot

At its core, a chatbot is built around conversation — you send a message, it responds, and that back-and-forth is the primary interaction. A chatbot on its own generally doesn’t take independent action in the world; it responds to what’s put in front of it, one exchange at a time.

What Defines an Agent

An AI agent is built to pursue a broader, often multi-step goal rather than just responding to individual messages — given an objective, it can plan a sequence of actions, use external tools (searching the web, running code, calling other software), and adjust its plan based on what it finds along the way, with much less turn-by-turn direction required.

The Key Practical Difference

The clearest practical distinction is autonomy over multiple steps: a chatbot waits for your next instruction after each response, while an agent can chain many steps together toward a goal on its own, checking in with you far less often, if at all, before the task is complete.

Why the Line Is Getting Blurry

Many current AI products combine both — a conversational chatbot interface that can also, when needed, act more like an agent by using tools or taking multi-step actions on your behalf — so in practice, ‘chatbot’ and ‘agent’ increasingly describe a spectrum of autonomy rather than two cleanly separate categories of product.

Bottom Line

A chatbot mainly responds to what you say, one message at a time, while an agent independently plans and executes multi-step tasks using tools — though many modern AI tools blend both behaviors depending on what you ask them to do.
