What is an AI copilot? Definition and explanation.

What an AI copilot does.

The name says it all: a co-pilot sits next to you, not in your seat. You set the course; the co-pilot helps along the way. While you’re writing, he suggests a way to phrase something. While you’re programming, he refines a function. While you’re drafting an email, he summarizes a long thread. The rule always applies: the co-pilot makes a suggestion, and you decide if it’s right.

That’s what makes a copilot accessible. You remain in control, so the barrier to getting started is low and the risks are manageable. The benefit lies in speeding up routine work and eliminating “blank-page” stress, not in having your judgment taken over.

Copilot versus agent.

This is the question you come across most often, so let’s be clear. A copilot supports and waits. An AI agent acts independently and plans the steps needed to achieve a goal on its own. The difference lies not in the underlying model, but in autonomy and supervision. Here’s an example: ask a copilot for help processing invoices, and it will suggest an accounting entry for each invoice that you approve. Give an agent the same goal, and it will process the entire batch on its own and only submit the borderline cases to you for review. The co-pilot keeps you at the wheel every step of the way. The agent takes the wheel on the parts where it’s safe to do so.

Examples of copilots.

The best-known example is probably Microsoft Copilot, which is integrated into Office. But it’s a broader category. Coding copilots such as GitHub Copilot, Claude Code, and GitLab Duo support developers. There are copilots for customer service, analytics, and design. We use coding copilots daily in our development process, alongside our own agents for the more complex, independent work.

Important: A copilot doesn’t have to come from a single vendor. The term describes a way of working (a human at the helm, with AI providing support), not a single product. So don’t get locked into a single ecosystem before you know what your use case really requires.

When a co-pilot is enough.

A copilot is the right choice when the work requires human judgment at every step, when errors are immediately visible and reversible, and when you want to speed things up without relinquishing control. For repetitive, rule-driven work that spans multiple systems, an agent is the faster solution.

The practical rule of thumb: start with a co-pilot if you’re unsure. You remain in control, learn where the AI’s strengths and weaknesses lie, and can later scale up to autonomous execution where it’s deemed appropriate. How you set this up safely depends on access and governance, and for that, MCP is the foundation.
