n8n Tutorial for Beginners: Build AI Agents & Automations

Stop doing repetitive work and start building your own AI-powered team! 🚀 In this complete, 90-minute masterclass, we go from absolute zero to building 8 fully functional AI agents and automations using n8n. Whether you are a total beginner or looking to scale your workflows, this step-by-step tutorial is designed for you. We don’t just talk about theory—we build. By the end of this video, you’ll have a solid foundation to automate your business, handle leads, and create custom AI support systems that work 24/7. What you’ll learn in this masterclass: ✅ The Basics: Setting up n8n and building your first lead-capture automation with Google Sheets. ✅ Conditional Logic: Routing data based on urgency using "If" nodes and Gmail. ✅ Custom Integrations: Using Webhooks to connect custom chat widgets from any website. ✅ Advanced Operations: Bulk data handling, filtering, and scheduled summary reports. ✅ AI Agents: Building "brains" for your automations using OpenAI and giving them tools and memory. ✅ RAG (Retrieval-Augmented Generation): Training an AI agent on your own PDF documents and using Supabase as a vector database. Why n8n? Unlike Zapier or Make, n8n gives you incredible flexibility, allows for self-hosting (keeping your data private), and charges per workflow execution—not per task. It’s the ultimate tool for serious automation.
