Summary If you're new to AI agents, this is the perfect place to start. In just 25 minutes, you'll learn exactly what an AI agent is, how it differs from traditional automations, and how to build one from scratch using n8n — no coding required. We’ll cover the core components of agent systems, how to set up guardrails, how agents interact with APIs, and what kinds of tools they can use. By the end, you'll have a working AI agent that can think, remember, and take action — and a clear understanding of how to build more. This is a hands-on, beginner-friendly guide designed to take you from zero to a working agent with practical, real-world applications.
