Quick answer
An AI agent is software that uses a language model to work towards a goal: it decides what steps to take, uses connected tools such as your CRM or email, checks the results and continues until the task is done. A chatbot answers a question, while an agent gets a piece of work finished.
How is an AI agent different from a chatbot?
Ask a chatbot about an unpaid invoice and it might explain your payment policy. Ask an agent, and it can look up the invoice, see that it is overdue, draft a reminder, and send it or queue it for approval. The difference is action: an agent is connected to systems and permitted to use them.
How does an AI agent work?
- It receives a goal, from a person or a trigger such as a new email.
- It plans the next step using the instructions and information it has.
- It uses a tool, such as searching a database or updating a record.
- It looks at the result and decides what to do next.
- It finishes, or hands over to a person when it is unsure.
Where do AI agents help businesses?
- Sales: researching leads, updating the CRM and drafting follow-ups.
- Support: resolving routine requests from start to finish.
- Finance: matching invoices and chasing missing documents.
- Operations: moving information between systems that don't talk to each other.
- HR: screening applications against agreed criteria, with a person making the decision.
What are the risks, and how do you control them?
An agent that can act can also make mistakes that matter. Language models can sound confident and be wrong, and a badly secured agent can be tricked by the content it reads. Good design limits the damage:
- Give the agent only the access it needs for the task.
- Require a person's approval for anything costly or hard to undo.
- Log every action so you can see what happened and why.
- Test on real examples, including awkward ones, before launch.
- Keep limits on spending, volume and number of attempts.
Do you need an agent at all?
Often not. If a task always follows the same steps, ordinary automation is cheaper and more predictable. Agents earn their place when the input varies and judgement is needed along the way. Our guide on which processes to automate first can help you tell the difference.
