Imagine having a smart, dependable assistant who helps you make better decisions, stay on top of what matters, and carve out more time for the work you actually enjoy. Now imagine you could have a whole team of those assistants, all working together to help you thrive.

That’s what AI agents can do.

You don’t need to be a developer to start using agents like these. You just need to know three things:

1. What agents are;

2. What they can do; and

3. How to get your hands on some.

Let’s explain all three.

_(Prefer to watch the video version of this explanation? Scroll down a smidge and hit play. I’ll be right there.)_

![What is an Agent](https://46075135.fs1.hubspotusercontent-na1.net/hub/46075135/hubfs/custom-video-thumbnails/What%20is%20an%20Agent-thumb.jpeg?length=1920)

## What is an AI agent?

An AI agent is just a piece of software that works toward a goal. That’s it.

But unlike a traditional workflow—which blindly marches through a checklist of pre-programmed steps—an agent can think a little. It can pick up on cues in its environment, collect and process data, make decisions on its own, and even get better over time. (Yes, this means it learns. No, it will not become self-aware and overthrow you.)

In short, agents are autonomous, goal-driven, and adaptive. They have _agency_. Think of them less like robots on rails and more like interns who _actually get it_.

## How to make an agent.

Someone has to make these agents. These days, it doesn't have to be a developer. It can be anyone with access to a computer—yes, even you.

If you’re ready to try building an agent, start with this question:

“What’s a recurring goal I need to achieve that requires some brainpower?”

Once you’ve got a goal in mind, write it out like this:

“When _this_ happens, I need to do _that_, so I get _these results_.”

Let’s unpack that:

- **Trigger:** What should kick things off?

- **Actions:** What should the agent do, decide, or discover to reach the goal?

- **Output:** What result should the agent deliver to prove it did its job?

For example, maybe you want to make sure you’ve listened to the most important podcast episodes before your morning commute. Your agent could be triggered every day at 5:30AM, scan your favorite shows, find new episodes on your key topics, analyze which ones are worth your time, and email you a tidy summary with links—all before you’ve finished brushing your teeth.

Trigger. Actions. Output. That’s it. That’s your agent.

## Where to find (or build) an AI agent.

If you’re a HubSpot user, good news: You already have agents built into your account. Better yet, you can teach them new tricks and customize them. Or, if DIY isn’t your jam, you can shop around.

Networks like [Agent.ai](https://agent.ai/) let you find agents built by others—entrepreneurial builders, HubSpot partners, or just people with more time on their hands. You can [browse and start using those agents right on Agent.ai](https://agent.ai/agents). Or, if you want to build your own agent, Agent.ai makes it possible (easy, even) for people to build their own agents, no coding required.

Whether you’re using built-in HubSpot agents, installing one off the shelf, or building a bespoke team on Agent.ai, you’re creating a support squad that helps you focus on what you’re best at—strategy, creativity, and the things that are uniquely human about your work.
