By Juan Carlos Guanoluisa Jacome on 2/7/2025

Waoo, this course was really factastic, because the teacher knows about n8n, compare with other courses, the teacher explain in a detailed way each feature of those components that he is using to build the workflow. Is a excelent milestone to go ahead for my self thank you so much

By Tiffany on 1/30/2025

Actually needed this for a school thing and chatGPT was being confusing. Googled AI Agents and found a sponsored ad and discount. Good value.

By Fred Pilinsky on 1/28/2025

I'm loving building this AI assistant, but as someone who isn't a coder I'd like some more understanding on how JSON works. Otherwiose, this is excellent.

By Michael Francis on 1/27/2025

Good. Building an AI Agent from scratch so far on N8N seems very useful. Will update at the end of the course again.
