# AI agents vs AI chatbots: what is the difference?

> A chatbot answers questions in a conversation; an AI agent works toward a goal and takes actions — it can look up records, update systems, book meetings or hand a case to a person. Many modern assistants combine both: a conversational front end with agent abilities behind it.

## Side-by-side comparison

|   | AI chatbot | AI agent |
| --- | --- | --- |
| Main job | Answer questions | Complete a goal |
| Actions | Few or none | Uses tools: APIs, CRM, calendar, databases |
| Steps | One reply at a time | Plans several steps |
| Memory | Short conversation context | Task state and history |
| Best for | FAQs, simple guidance | Qualification, support resolution, operations |
| Controls needed | Approved answers | Approved answers plus permissions, approvals and logs |

## Which one should your business choose?

Choose a **chatbot** when people mostly need quick, accurate answers from your information. Choose an **agent** when the value comes from *doing* something next — qualifying a lead, creating a ticket, collecting documents or updating a record. Starting with a focused chatbot and adding agent actions later is often a sensible path.

## How do the costs compare?

At Agentic AI Tech Hub a chatbot or single automation with one or two integrations is typically a **Small** project ($2,000–$5,000, usually 1–2 months), while an AI agent with several integrations is typically **Medium** ($6,000–$15,000, usually 3–4 months).

## Frequently asked questions

### Can a chatbot be upgraded to an AI agent?

Yes. The conversation layer can stay the same while tools, permissions and workflows are added behind it.

### Are AI agents riskier than chatbots?

They can do more, so they need more controls: limited permissions, approvals for important actions and logging of every step.
