What is an AI agent? The definition for business leaders
An AI agent receives a goal, chooses the steps and acts in your tools, under rules you set. The definition, examples, and what it does not do.
The word is everywhere, often for very different things. Here is a definition a business leader can use, without jargon, and the questions to ask to find out whether an agent would be useful to you.
What is an AI agent?
An AI agent is software that receives a goal, chooses the steps to reach it and acts in your tools. It relies on an AI model to understand a text, a document or a request, then it chains actions together: read, sort, check, write, update, pass on.
Three traits set it apart from a simple tool:
- It acts, instead of only answering: it files an invoice in the accounting software, sends a reminder, updates a record.
- It decides on the route within a given framework: if a piece of information is missing, it asks for it; if a case is out of the ordinary, it flags it.
- It follows your rules: your payment terms, your prices, the way you answer a customer.
A concrete example
Example: a supplier invoice arrives by email. The agent extracts the amount, the date and the supplier, checks that the matching purchase order exists, enters the invoice in your accounting tool and puts it on hold for approval. If the amount does not match the order, it does not decide: it alerts the person in charge of purchasing, with the details of the discrepancy.
That is exactly what a person does. The difference: the agent does it at any hour, the same way every time, and it keeps a record of every step.
What an AI agent does not do
A well-designed agent does not decide alone on anything that commits the company. Paying a supplier, signing, setting a price, publishing on the company’s behalf: it prepares, a person approves. This is a design rule, not an optional setting. We explain it in detail on our Governance page.
Nor does it replace knowledge of your business. An agent that does not know your rules gives an answer that is right for everyone, and wrong for you. That is why every implementation starts by looking at the real work with the person who does it.
AI agent, assistant, automation: the difference in one sentence
- An assistant (such as ChatGPT or Copilot) answers when you ask it a question.
- A traditional automation always runs the same sequence of actions, without understanding free text.
- An AI agent understands a request, chooses the steps and acts, within a set framework.

Task, process, domain: three sizes of agent
What you hand over to an agent comes in three units:
| Unit | What it is | Example |
|---|---|---|
| A task | a trigger, an action, a result | extracting the data from an invoice received by email |
| A process | several steps, with decisions and special cases | from the invoice received to the bank reconciliation |
| A domain | a whole area of the business, with its rules | customer relations and support |
This grid helps you choose the right project size: Task, process or domain: scoping an AI agent project.
How do you know whether an agent would be useful?
Ask yourself five questions about the work you would like to hand over:
- Does it come round at least several times a week, in a comparable form?
- Is the information in a tool, or only in someone’s head?
- If the agent gets it wrong once in twenty times, what happens?
- Can we say what we will measure, and where the figure stands today?
- Can we go back tomorrow morning, without damage?
If most of the answers are yes, you probably have a good candidate. The AI agent catalogue shows, department by department, what an agent can take on. And if you would like an outside view, the Flash Diagnostic is free: a one-hour interview, then a written report within 72 hours.
Frequently asked questions
Is an AI agent a robot?
No. It is software, with no physical form. It works in your existing tools: it reads an email, fills in a spreadsheet, drafts a reply, updates a customer record.
Can an AI agent replace an employee?
It takes on tasks and processes, not a whole job. It absorbs the repetitive work; decisions that commit the company stay human, and the person who used to do the work supervises it.
Do you need technical skills to use an AI agent?
Not to use it. You do need someone who knows the work being handed over, its exceptions and its rules: that knowledge is what makes a good agent.
