AI agent or chatbot: what’s the difference, and which do you need?

A chatbot talks. An AI agent talks and does things. That’s the main difference, and it affects what you’ll pay and what can go wrong.

What a chatbot does

A modern chatbot reads your website and documents, then answers questions in natural language. It might tell a customer your opening hours, whether you service their suburb or what your returns policy says.

It’s useful and fairly low risk, because the worst outcome is usually a wrong answer, and you can reduce that by limiting it to your own content.

What an AI agent does

An agent can also take action using your other systems. It might check your calendar and book a job, look up an order, create a lead in your CRM or send a confirmation SMS.

Because it can change things, an agent needs more care: clear limits, tested connections and a way to hand over to a person.

Which do you need?

Start with a chatbot if most of your enquiries are the same questions, you mainly want fewer interruptions, and you don’t need it connected to other systems yet.

Choose an agent if the value comes from finishing the job, such as booking the appointment, not only answering the question.

A sensible path

Many businesses start with a chatbot that answers questions and captures leads. Once it’s answering well, you can give it one action, such as booking appointments, and add more as you build trust.

Questions to ask any supplier

• What happens when the AI doesn’t know the answer?
• How does a customer reach a real person?
• What can it access, and what can it change?
• Where is our data stored, and is it used to train AI models?
• Can we switch AI models later?

If a supplier can’t answer these clearly, keep looking.
