AI agent vs chatbot: what is the difference

In marketing copy "AI chatbot" and "AI agent" sound the same. They are not. The difference is not the model — it is whether the tool can act or only talk.

In short

• A chatbot holds a conversation: answers questions, captures contacts, shows menus.
• An AI agent performs actions: creates a deal, finds a document, places an order, triages an inbox and decides where each message goes.

When a chatbot is enough

If the goal is to take repetitive questions off your team and stop losing after-hours enquiries, an AI chatbot covers roughly 80% of sales and support cases at a lower price.

When you need an agent

An agent earns its cost where an answer must be followed by an action a human currently performs: parsing an inbox into structured leads, retrieving and sending documents, checking stock and issuing invoices, assembling a report from three systems. See AI agent development.

Risk and how it is contained

1. Allow-list of actions. The agent does only what is explicitly listed; everything else escalates.
2. Confirmation on irreversible steps such as sending an invoice or changing a price.
3. Full audit log of every action and its reason.

FAQ

Can we start with a bot and grow into an agent?

Yes, and it is the sensible path: the knowledge base and flows carry over, so you pay for tools and integrations rather than starting again.

How do I decide?

Take your last 50 enquiries and count how many require an action in a system after the answer. Under a third — a chatbot is enough.
