# AI Agent

An AI agent is software that autonomously handles customer inquiries from start to finish. Unlike a chatbot that follows scripted paths, an AI agent reasons through problems, searches your knowledge base, pulls data from your systems, and takes actions like updating an order or issuing a refund, all without human intervention. It is customer support that runs itself, resolving issues instantly at any hour.

**Key point:** An AI agent is autonomous. It does not hand off to a human for every edge case.

## How does an AI agent work?

AI agents combine three layers to handle support inquiries end-to-end:

| Layer         | What it does                                                                                                                              |
| ------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| Understanding | Reads the customer's question in natural language and determines intent, context, and required actions.                                   |
| Reasoning     | Decides the best path to a resolution, whether that means searching documentation, pulling account data, or running a workflow.           |
| Action        | Executes tasks across your systems through APIs, such as updating a ticket, processing a return, or escalating only when truly necessary. |

The difference from a chatbot: the agent decides what to do next based on the situation, not a decision tree you coded in advance.

## Why does an AI agent matter?

AI agents resolve the majority of routine inquiries instantly, so customers never wait and your team never sees those tickets. They work 24/7, scale without adding headcount, and improve as they learn from real conversations. For most support teams, an AI agent is the path to handling growth without hiring linearly.

## Frequently asked questions

### What is the difference between an AI agent and a chatbot?

A chatbot follows scripted paths and hands off complex issues. An AI agent reasons through problems, accesses real data, and takes actions like updating orders or searching knowledge bases, all autonomously without escalating to a human.

### Can an AI agent work with my existing tools?

Yes. AI agents integrate with support platforms, knowledge bases, CRMs, and order systems through APIs. They pull data and take actions across your existing stack, so customers get complete answers in one conversation.

### Do AI agents replace human support teams?

No. AI agents handle routine inquiries so your human team can focus on complex, high-touch cases. They are the next hire you will not need to make, augmenting your team rather than replacing it.
