Course Description

This course is a complete, hands on guide to mastering N8N and AI automation.

Automation is one of the most in-demand skills today, and n8n has quickly become one of the most powerful tools available. It is open source, flexible, and allows you to connect hundreds of apps and services together. When combined with AI models like OpenAI, Claude, Grok, Gemini, and Ollama, the possibilities are endless.

This course takes you from the very basics of n8n to advanced AI powered automations. You will not just learn concepts, you will build real projects step by step. Every lecture is designed with practice in mind, so by the end of the course, you will have built a portfolio of automation workflows that you can use in your own business or freelance career.

We will cover:

  • Installing n8n locally, in the cloud, or on a VPS

  • Trigger nodes, credentials, and integrations

  • Building AI chatbots with tools and website integration

  • Retrieval Augmented Generation (RAG) with n8n

  • Error handling for production-ready workflows

  • Dozens of projects: Telegram bots, Discord bots, Slack bots, WordPress automation, Google Sheets visualization, and more

  • Human In The Loop workflows (HITL)

  • Advanced projects like LinkedIn scrapers, AI crypto sentiment analysis, and AI meme generation

By the end, you’ll be confident in building automations that save time, boost productivity, and bring AI into your workflows.

I like the hands on approach, but maybe show us how to create credentials before you show us how to make workflows. That first part was a bit long and hard to follow for me because I felt like an important part was missing to fully grasp it. Though it was given later, that were like 20 min of stress that I could've saved myself from. Or tell us that this part is only for show and we will do this all together later again.

Great training so far; will update if need throughout course. Needs some additional context for local configuration, particularly configuring google credential/api accessing, though nothing that cant be resolved with a quick google search (if youre lost though, you need to enable "test users" for your project in google cloud/console which exists in "Google Auth Platform > Audience" settings).

This is a very useful and well-explained n8n course. The instructor explains each step clearly, making it easy to follow even for beginners. I learned a lot about building workflows, connecting different tools, and understanding how automation works in real projects. The lessons are practical, detailed, and easy to understand. Highly recommended for anyone who wants to learn n8n properly.

By Csonka Viktor on 6/5/2026

This course was very interesting and helpful. The explanations were clear and easy to understand. The most interesting part for me was the last few videos, where real-world projects were demonstrated. Overall, it was a very useful course for learning workflow automation with n8n, AI agents, and LLMs.

Hace muy fácil entender las características de n8n8. Me dio muchas ideas acerca de cómo podría llevar a cabo la actualización y generación de mi propio contenido. A veces va algo rápido pero precisamente eso ayuda para ir directo al grano sin perder tiempo.

By Isaac Sanchez on 3/23/2026

Fue muy bueno para sentar las bases de lo que es n8n y su funcionamiento. Lo que se tiene que procurar es actualizar las APIS que se usan en el video porque por ejemplo Custom search API ya no está habilitada por lo tanto uno no puede completar los ejercicios de la lección.

By Doron Kimia on 3/22/2026

This masterclass provides an exceptional and practical framework for implementing N8N and AI automation in production environments. I highly recommend it to any professional seeking to build scalable and intelligent workflows with absolute efficiency.

By Anand Thakur on 3/21/2026

I found this course to be very helpful and well-organized, with a strong focus on practical learning. The concepts were explained in a clear and simple way, which made the tool easy to understand and apply in real-life situations.

By Arnold Stucky on 2/28/2026

A lot of what is displayed is dated. I also feel that this did not fit my specific need but that was due to me being new to n8n. I would have loved to see more content on the specific tools for data handling within n8n perhaps being able to query databases and manipulate the data in some way. Training was very clear and informative.

By Diwakar M on 1/24/2026

Really solid course for learning n8n with AI automation. Everything is explained step by step with real projects, not just theory. I learned how to build Telegram bots, WordPress automation, scrapers, crypto sentiment analysis, and AI workflows confidently. The best part is the focus on real-world, production-style automations and error handling. After completing this course, I feel confident creating my own workflows and using them for freelance or business use. Highly recommended if you want practical n8n + AI skills.
