What Is An AI Agent?
AI agent: An AI agent is software that takes a goal from you, works out the steps, and carries them out using tools such as a web browser, email or a calendar, checking its progress as it goes. Where a chatbot answers, an agent acts.
The Three Parts Of An Agent
Most definitions, including IBM’s and Google Cloud’s, describe the same pieces. A model that reads and reasons, so it understands “send Maria the revised quote.” Tools it can use, such as a browser, your inbox or a spreadsheet. And a loop: it tries a step, looks at the result, and decides what to do next until the job is done or it needs you.
What It Looks Like In A Small Business
You type: “Find every invoice from last month that’s still unpaid and draft a polite reminder for each.” An agent opens your accounting app, filters the list, reads each customer’s name and amount, and writes the drafts. A chatbot could only tell you how to do it yourself.
AI Agent Vs Agentic AI
You’ll also see “agentic AI.” It names the wider idea of AI that sets goals, plans and acts with little hand-holding. Google Cloud puts it this way: agents are the building blocks, and agentic AI is the coordinated use of them, often several agents sharing a bigger job.
Where Agents Still Need You
Agents make mistakes. They misread a page, or follow bad instructions hidden in an email. That’s why well-built agents ask before anything hard to undo, such as sending, paying or deleting. IBM recommends human approval before high-impact actions, and Anthropic’s own advice is to start with the simplest setup that works and add freedom only where it clearly helps.
Worth Remembering
- An agent acts; a chatbot talks.
- It works in a loop: plan, act, check, repeat.
- What it can do depends on which tools and accounts it can reach.
- Good agents stop and ask before risky steps.
- “Agentic AI” is the broader idea; an agent is one working unit of it.
In Octopus Prime
Octopus Prime runs AI agents on a computer you own. Each agent uses its own browser and your own login to work in the apps you already use, one item at a time, and it waits for your OK before it sends, publishes, deletes or moves money.

Questions
Is ChatGPT an AI agent?
The regular ChatGPT conversation is a chatbot: it answers inside the chat. OpenAI also offers an agent mode that uses a browser to complete tasks, so one company can make both.
Can an AI agent work without me watching?
Yes, that’s the point, but you decide how far it goes. Most people let an agent read and draft freely and keep sending, paying and deleting behind an approval step.
Do I need to know how to code to use one?
Not with tools built for non-technical users. You describe the job in plain words, the way you’d brief a new hire.
Is agentic AI the same as an AI agent?
Close, but not quite. Agentic AI is the general approach; an AI agent is one piece of software that works that way.
AI agents that work in your apps. On computers you own.
