CopilotorAgent
A copilot assists a person while they work: they keep their hands on the controls, and every suggestion goes through them. An agent pursues a goal in their place: they set the aim and come back to a result, without approving each step.

| Who holds the wheel | The person, at all times | The system, between two checkpoints |
| Rhythm | Suggestion by suggestion | A task that lasts |
| What you approve | Every suggestion | The result, and the sensitive points |

| Adoption | Fast, low risk | Slow, demands guardrails |
| What fails | One suggestion, rejected without harm | A chain, whose error spreads |
On the ground four situations
A tool offers the next lines of code while the developer types, line after line.
Floor 4 · The Organisationa mosaic: AI is only one tile among manyCopilotEvery suggestion is accepted or rejected straight away. The developer never left the keyboard.
The same developer describes a fix to be made, goes to lunch, and comes back to a complete proposed change with its tests.
Floor 3 · The Agentthe block caught in a loop: it starts again until it gets thereAgentThe goal was given once, and the system chained several steps on its own. Approval bears on the result, not on each move.
A checker suggests rewordings in a word processor.
Floor 4 · The Organisationa mosaic: AI is only one tile among manyCopilotThe useful counter-example: how rich the suggestions are changes nothing. As long as the person decides every time, it is assistance.
A tool that suggests as you write and can also, on request, refactor a whole module.
BothThe same product offers both regimes. It is the most common case, and it is why you have to look at what happens in a given use rather than at the label on the product.
The test that settles it
Watch whether the person can step away while the work moves forward. If the system waits for approval at every move, it is a copilot. If it carries on without them, it is an agent.
The trap
The word “copilot” is reassuring and often serves to sell an agent. The point to check is not the name of the product but the place where the human steps in: at every step, or only at the end.
