Course Description

Amplify your business with n8n and ElevenLabs in just 3 weeks - no prior knowledge needed


It’s easy to see why n8n has been such a hit. In a matter of minutes, you can build an AI Agent from scratch with real-world business value. It’s seriously satisfying.

And in just three weeks time, you will be a pro at it!


Week 1 is about AUTOMATING your business.

You’ll make AI Agents that integrate with Google Sheets, Email, Slack, Telegram, Pushover and Marketwatch, using OpenAI models and open-source models.

Gain a deeper understanding of LLMs and go live with your first AI Agent on n8n with OpenRouter or OpenAI!


Week 2 is about ACCELERATING your business.

You’ll build Voice Agents with expertise in your business, with a RAG pipeline, powered by Gemini and OpenAI embeddings, and integrated with ElevenLabs and Supabase.


Week 3 is about AMPLIFYING your business.

You’ll build a complete multi-agent system with MCP, self-hosted n8n and Ollama. You’ll put advanced Agentic AI techniques into practice, like Context Engineering and Sub-agents with DeepSeek.


We’ll wrap up with a Capstone with high commercial impact - a classic Go-To-Market use case taken further than ever before, autonomously finding leads using MCP servers with Tavily, FireCrawl and Hunter, creating leads in Pipedrive and nurturing them.


The most surprising thing is that we deliver production-grade commercial functionality in under an hour. And without writing a line of code - just a couple of expressions and plenty of JSON.

Excellent parcours ! L'enthousiasme communicatif d'Edward ne doit pas faire oublier à quel point le parcours est progressif et bien fait. Jamais décourageant avec toujours une belle récompense qui pousse à continuer. L'objectif était pour moi de comprendre la place de chaque brique dans le légo d'ensemble et l'ingénierie nécessaire pour leur mise en place puis d'évaluer les potentiels et limites des workflows agentiques dans un contexte BtB. Il nous montre la voie, à nous de l'explorer. Je le recommande absolument !

By Alexandre Dutier on 8/28/2026

Thanks, Ed, for this fantastic course! Throughout the 14.5 hours of content, your enthusiasm never faded and your positive attitude was always evident. The energy and passion you bring to every lesson are truly contagious, making it easy to stay engaged from start to finish. The integrations and use cases you covered were both practical and highly relevant to real-world scenarios, which made the learning experience even more valuable. This course was an absolute pleasure to follow, and the quality of the content kept me motivated throughout its entire length.

Excellent AI Builder course by Ed Donner! I thoroughly enjoyed this course. Ed delivers the content in a structured manner easy to follow and presents material with such enthusiasm and excitement, which makes learning fun. As it was my first time exploring Agentic AI I found the course great as a beginner. I really liked the integrations with other application, especially with ElevenLabs. As with most courses, and especially where AI is involved, material can be out of date quickly. I found a few areas where elements have changed or were different to course content. However, this is great experience for you to explore, resource and find solutions yourself.... and gives immense satisfaction when you find working solutions. I would definitely recommend this course to anyone exploring Agentic AI. Thanks to Ed for creating such a great course!

By Alexandre Menezes de Queiroz on 8/7/2026

Considering the price of this course and everything that was presented, I cannot ask much of it. My evaluation was based on that. I would like to emphasize again that it is hard if not impossible to offer a good tuition with no extra costs in an AI world, where costs are too high to keep the whole infrastructure. Having said that, sometimes I only felt it was too much repetitive explanation instead of being more objective. In addition, maybe the course could focus more on the usage of AI free resources that could last for the time someone do this course. For instance, as I needed to use n8n much over the hours of this course, I reached a point where I needed to use only the docker image version and then it was not possible to me quickly to create https webhook endpoints to integrate with elevenlabs, and even less possible to have a phone number to be imported from twilio to perform something similar to what was presented in some videos.

As a software engineer, this course was an incredible hands-on journey into the modern AI stack. Ed Donner does an amazing job explaining complex concepts clearly. Learning to build AI agents in n8n, implementing RAG and MCP architectures, and integrating tools like ElevenLabs was both practical and empowering. I even used ElevenLabs to build a voice-powered interview simulator to practice for real technical chats! Highly recommended for anyone looking to build real-world AI applications quickly and effectively

By Siddharth Begwani on 7/27/2026

Brilliant course. This is the fourth course offered by Ed that I have taken and like all the others, it is superbly delivered. I must add that this also seemed to be the toughest of the courses, even more difficult than the Agentic AI and LLM Engineering courses which involve significant coding (I am a non-technical person). The number of integrations can be a bit overwhelming at times but once you manage to get things working, it is very satisfying and exhibits the power of visual AI-driven workflow design solutions like n8n.

I run an AI engineering studio, so I came in already building production systems, but n8n and ElevenLabs agent architecture was a real gap for me. Ed doesn't just show you the tools. He teaches how to think about agentic systems: context engineering, security, MCP, and how to build something that survives contact with a real client instead of staying a demo. Three weeks, intense pace, and it delivers. I built a voice AI booking agent using ElevenLabs Conversational AI, Twilio, and n8n during the course, and the patterns Ed teaches around context engineering and security went straight into that build. What sets this apart from other agent courses is that it doesn't stop at "here's how you call an API." It covers the parts that actually matter in production: auth, security boundaries, structuring an agent so it's maintainable rather than a pile of prompts glued together. Highly recommend, whether you're technical or completely new to this.

Excellent Course with a Fantastic Finale This was a very well-structured course with a very appropriate pace. The instructor did an excellent job of explaining the concepts clearly without rushing through the material, while also repeating important points at the right moments to reinforce what had been learned. The entire course had a clear and consistent thread running through it, which made it easy to follow and understand how the individual topics fit together. Everything built naturally toward the end, culminating in a truly fantastic finale that brought all the different elements together. On top of the excellent content and structure, the instructor is extremely charming and has a very pleasant voice, which makes listening to the course particularly enjoyable. Overall, a highly engaging and well-designed course that I can absolutely recommend!

By Wasi Abbas on 7/23/2026

Excellent course with clear explanations and practical, real-world AI agent projects. I've learned a lot and really appreciate the instructor's teaching style. It would be even better if common issues (API quotas, node errors, webhook/schema problems, and setup troubleshooting, especially slack was so disturbing for me, u should have make video on how to solve the problem you were facing) were covered in more detail for beginners. Secondly, project on whatsAPP automation is missing.You should make video on it.

By Aroh Shukla on 6/6/2026

I have been searching for high quality AI courses for quite some time, and I can confidently say that Ed's courses are among the best I have taken. The concepts are explained in a very simple and easy-to-understand manner, making even complex topics approachable for beginners. What really stands out is Ed's enthusiasm and energy throughout the lessons, which keeps the learning experience engaging and enjoyable. I genuinely love this course and highly recommend it to anyone looking to learn AI, Generative AI, or Agentic AI in a practical and accessible way.
