In the rapidly evolving world of artificial intelligence, the ability to build and deploy “AI Agents”—autonomous systems that can think, use tools, and complete complex tasks—is becoming one of the most valuable skills in the tech industry.
Nate Herk’s comprehensive 8-hour masterclass, “Build & Sell n8n AI Agents,” is a game-changer for anyone looking to enter the AI automation space without writing a single line of code. Whether you’re an aspiring entrepreneur or a business owner looking to streamline operations, this course provides a roadmap to creating high-value AI solutions.
Why n8n? The Power of No-Code Automation
n8n is a powerful, node-based workflow automation tool that serves as the “brain” for your AI agents. Unlike simple automation platforms, n8n allows for complex logic, deep integrations, and—most importantly—seamless connection to Large Language Models (LLMs) like OpenAI’s GPT-4 or Anthropic’s Claude.
In the course intro, Nate shares his incredible journey: earning over $500,000 in revenue in just eight months by building and teaching these exact systems [00:09].
What You’ll Learn: From Zero to Pro
The course is structured to take you from a complete beginner to a master of “agentic” systems. Here’s a breakdown of the core pillars covered:
1. Foundations and Setup
Nate starts by walking through the n8n UI, setting up a free trial, and explaining the core concepts of workflows [00:19]. You’ll learn how to name workflows, manage credentials, and navigate the drag-and-drop interface.
2. Working with JSON and Data
A crucial part of AI automation is understanding how data moves. Nate breaks down JSON, the universal language of LLMs [30:00]. You’ll learn how to:
- Interpret “keys” and “values” [47:29].
- Use “Set” nodes to organize data [23:38].
- Map data between different tools using a simple drag-and-drop schema [23:26].
3. Building RAG Systems (Retrieval-Augmented Generation)
One of the most powerful features of modern AI is the ability to chat with your own data. Nate demonstrates how to:
- Trigger workflows when a file is dropped into Google Drive [59:07].
- Use Text Splitters (specifically Recursive Character Text Splitters) to “chunk” documents so the AI can process them efficiently while maintaining context [01:05:07].
- Connect these chunks to a Vector Database (like Pinecone) for long-term AI memory [59:12].
4. Advanced Agentic Architecture
Moving beyond simple bots, the course dives into:
- Tool Calling: Teaching an agent how to decide when to use a specific tool, like Perplexity for research or an email node for outreach [05:08].
- System Prompting: Crafting the “personality” and “instructions” that guide how your agent behaves [01:16:38].
- Multi-Agent Systems: Setting up architectures where multiple agents work together to solve complex problems.
Scaling: The Hybrid Approach
As you move toward building for large-scale clients, Nate offers a “pro tip” for the future. While n8n is incredibly modular and fast for building MVPs (Minimum Viable Products), scaling to millions of users might eventually require a hybrid approach [08:25:06]. Combining n8n’s orchestration with custom Python scripts for heavy data processing creates a robust, high-performance system [08:25:28].
Conclusion: Start Your Journey Today
This 8-hour course isn’t just a tutorial; it’s a career-starter. By the end, you’ll have over 15 AI automations ready to be deployed or sold to clients [00:19].

Key Takeaway: You don’t need to be a coder to be an AI engineer. You just need the right tools and the willingness to build. As Nate says, “You can do it all” [08:23:55].
