# What is AI agent?

An AI agent is a program built around a language model that can take actions, not just answer. It receives a goal, decides which tools to call, such as a calendar, CRM or email, observes the result and continues until the task is done or it needs a human.

## Agent versus assistant

An assistant replies. An agent acts. The difference is tools: an agent has permission to read and write in your systems, which is why scoping those permissions is the first design decision.
In practice most business agents are narrow: one job, three to six tools, clear stop conditions. Broad, do-anything agents are harder to trust and rarely worth it for an SME.

## FAQ

**Can an AI agent make mistakes in my CRM?**

It can, which is why we give agents the narrowest permissions that do the job, log every action, and route low-confidence cases to a person before anything is written.
