In this hands-on lecture, you’ll build your very first real AI agent: a Lead Qualification Assistant. This agent will read customer call transcripts and automatically decide if each conversation is a strong lead or not, saving your sales team countless hours.

We’ll walk through the entire build step by step:

• Setting up a manual trigger

• Creating test data using a simple code node

• Designing the AI agent to analyze customer transcripts

• Writing a clear system message to guide the agent’s decisions

• Connecting to OpenAI to power your agent’s brain

• Parsing the output into structured, usable data for your team

You’ll also see how to import the pre-built JSON file if you want to get started faster. For those who prefer a detailed written guide, we’ve included a step-by-step Word document in the resources so you can follow along and reference instructions at any time.

By the end of this lecture, you’ll have a fully working AI agent that qualifies leads automatically – and you’ll understand exactly how each piece works so you can customize it for your own business workflows.

In this lecture, you’ll build your second AI agent: an E-commerce Chat Assistant. This agent goes beyond backend automation and interacts directly with your customers, just like a live chat rep on your website.

You’ll learn step by step how to:

• Set up a chat trigger to start conversations with customers

• Design your AI agent to handle product questions, pricing inquiries, and bulk order requests

• Write an effective system message that guides the agent’s responses with your business information, products, and discount rules

• Connect the agent to OpenAI as its brain to power realistic conversations

• Add memory so your assistant remembers what customers say, enabling natural multi-step conversations

• Use an if statement to detect when a customer is ready to place an order and trigger the next action, like sending them to checkout or notifying your sales team

You’ll also see how to test your agent live, ensuring it responds accurately and flags serious buyers. By the end of this lecture, you’ll have a working ecommerce chat assistant that enhances customer experience, saves your team time, and increases conversion rates — all built visually inside n8n without writing a single line of traditional code.

In this lecture, you’ll see a powerful demo of an advanced Retrieval-Augmented Generation (RAG) agent in action. Unlike simpler AI agents that rely only on static system messages, this RAG agent connects to your business’s real knowledge base to answer questions dynamically.

You’ll learn:

• What a RAG agent is and how it works

• How this agent connects to Google Drive and Supabase to retrieve up-to-date documents, policies, pricing sheets, and internal resources

• How it uses retrieved data to provide accurate, context-rich answers to user questions

• How technical users can integrate tools that allow the agent to generate SQL queries for answering database questions in real time

This demo will show you how RAG agents can go beyond basic chat automation to become powerful knowledge assistants that pull live data directly from your business systems, enabling more advanced and scalable AI solutions.
