Learn to build AI agents using n8n, a powerful workflow automation platform, in this comprehensive 50-minute tutorial designed for beginners. Start by understanding the fundamentals of n8n, including its interface, benefits, and core concepts like nodes and workflow creation. Explore different node types including trigger nodes, action nodes, utility nodes, code nodes, and agent nodes, then discover how to configure inter-node connections and dynamically map data between components. Build your first automation by creating triggers, working with HTTP requests to connect to weather APIs, using code nodes for custom messaging, and integrating Gmail functionality. Progress to constructing your first AI agent by adding chat nodes, configuring AI agent nodes with chat models, implementing memory capabilities, and incorporating agent tools like HTTP requests and Gmail integration. Master advanced concepts such as letting models decide parameters automatically and testing complete agent systems. Gain practical experience through hands-on examples including a weather report automation and a fully functional AI agent, while learning best practices for node configuration, data mapping, and system testing that will prepare you for more advanced agent building projects.
