# What is an AI agent?

> An AI system that takes actions, not only answers: searching, filling forms, sending messages, or using other software on your behalf.

## Why it matters for Christians

An agent acting for you is still acting in your name. You remain responsible for what it does.

## What to do

Before you let an agent act for you, decide what it may do without asking: read only, or send and buy too. Check its work the first few times, the way you would with a new helper. Keep anything that speaks for you to people, such as a message to a grieving friend, in your own hands.
