What are Agents, Tasks and Crews?

No dark-mode styles — this email renders the same in a dark client.

Three concepts. Once these click, everything else makes sense.

Hey!

Before you go any further, let's make sure the building blocks make sense — because this is where a lot of people get confused.

CrewAI has three core concepts:

- Agents — AI workers, each with a role, a goal, and optionally tools. Think: a Researcher agent, a Writer agent.
- Tasks — specific instructions you give an agent. "Research the top 5 competitors" is a task.
- Crews — a team of agents working through tasks together to produce an output.

That's really it. An Agent does work. A Task defines what work. A Crew coordinates it all.

A quick example: A content Crew might have a Research Agent that finds sources, and a Writer Agent that turns those into a blog post — automatically, end to end.

Once you see this in action, it clicks fast.
