AI Support & Agents

AI Agent

Definition

An AI agent is a software system that uses a language model to understand a request, decide what to do, and take actions — calling tools, retrieving data, and completing tasks — rather than just returning a single scripted answer.

Also known as: autonomous agentAI support agentagentic assistant

How it works

An AI agent pairs a language model with a reasoning loop and a set of tools. It interprets the user's goal, plans the steps needed, calls tools or APIs to gather information or make changes, checks the result, and continues until the task is complete or it needs a human.

In support, that means an agent can read a ticket, look up the customer's account through a connected system, apply your policy, and resolve the request — not just describe how to do it.

Why it matters for support

AI agents move automation from answering FAQs (deflection) to actually completing tasks (resolution). Because they act on live data, they can handle the multi-step, account-specific requests that used to require a human.

Plans and executes multi-step workflows
Reads and writes real data through tool and API calls
Hands off to a human with full context when confidence is low

Frequently asked

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

A chatbot returns an answer to a message; an AI agent plans and takes actions across steps and tools to resolve a request end to end. Agents can do what chatbots can, plus act on live systems.

Are AI agents reliable in customer support?

They're reliable for well-scoped tasks with clear policies and good data sources, especially when paired with guardrails and confident human handoff for edge cases.
