A chat answers, an agent does the job#
You have probably used ChatGPT or a similar chat. You ask a question, it answers, and then you copy the answer somewhere and do the rest yourself. When you close the tab, nothing more happens.
An AI agent works differently. You give it a job, not a question. It then uses a computer the way you would: it opens files, searches the web, writes documents, runs programs, and saves the result. When the job is finished, it tells you.
Chatbot, assistant, agent: where the line falls#
Three different tools get called "AI":
| Chatbot | Assistant | Agent | |
|---|---|---|---|
| What it does | answers you | repeats one prepared task | carries out a whole job |
| Can it use a computer | no | no | yes — files, programs, the web |
| Does it plan its own steps | no | no | yes |
| When does it work | when you ask | when you ask | on its own, around the clock |
Picture a new colleague who never gets tired#
The easiest way to picture an agent is a new colleague. You say what you want: "Every morning, find three news stories about my industry and write me a short summary." The agent does the work, and you look at the result. If something is off, you say so in one sentence, and the next result is better.
You do not need to know how an agent works inside, just as you do not need to understand an engine to drive a car. You need to know what you want and be able to tell whether the result is good.
Where the agents live#
Your agents work on a small rented computer on the internet, called a server. It stays on when your laptop is off, so the agents can keep working at night. You talk to them from your phone, in a chat app such as Telegram, the same way you would message a friend.
Our own example#
This course comes from a small business that runs this way. Seven agents on one small rented server research topics, write video scripts, make the videos, check each other's work, and prepare everything for publishing. The person in charge, The Operator, does not edit or write; the job is reading a short report on the phone and approving what is ready.
The one rule worth remembering#
The agent does the work; you keep the final word. Anything that spends money, goes out to other people, or deletes something waits for your yes. That is what makes it safe to let agents work while you do something else.

This is one of the free lessons. The full course goes from first principles to a system you can run and repair: the machine, your first workflow, an agent team, a production line, the money side, and keeping it all running.
