What is an AI agent? A plain-English guide to the word everyone is using
An AI agent doesn't just answer questions: it takes steps for you, like searching, clicking, filling in forms and using apps. Here's how agents work, what they can do today, and how to use them safely.

Key points
- A chatbot answers; an agent acts, using tools and apps on your behalf
- Agents work in a loop: plan, take a step, check the result, repeat
- They already prepare briefs, write code and fill in forms
- Give them only the access they need, and approve sensitive steps yourself
"Agent" is the AI word of the year. Companies call almost everything an agent now. So what is one, really?
Chatbot vs agent
A chatbot answers. You ask a question, it writes a reply, and you do the rest.
An AI agent acts. You give it a goal, and it takes the steps itself: searching the web, opening files, clicking buttons, filling in forms or sending a message, then reporting back.
| Chatbot | Agent | |
|---|---|---|
| You give it | A question | A goal |
| It does | Writes an answer | Takes several steps with tools |
| Example | "What's a good hotel in Lisbon?" | "Book a hotel in Lisbon under $150 for May 3–5" |
How an agent works
Most agents run the same loop:
- Plan: break the goal into steps.
- Act: use a tool, such as a browser, an app or a file.
- Check: look at the result.
- Repeat until the job is done, or ask you when it's stuck.
To use tools, agents rely on shared standards such as MCP and Agent Skills, which we explain in MCP and Agent Skills, explained.
What agents can do today
- At work: at Uber, ChatGPT Work prepares meeting briefs and presentations from email, files and calendars (read more).
- For coding: tools like Codex and Claude Code write, test and fix code across many files.
- For everyday tasks: personal agents can compare prices, fill in forms and sign in to websites.
What they still get wrong
Agents can misunderstand a goal, click the wrong thing or confidently report a job as done when it isn't. The longer the task, the more chances for a mistake. That's why the best agents stop and ask before anything important.
How to use agents safely
- Give the least access needed. An agent planning a trip doesn't need your bank login.
- Never paste passwords into a chat. Tools like 1Password for Agents let an agent sign in without seeing your password.
- Approve payments and sends yourself.
- Check the result, not just the agent's summary of it.
