AI Automation: Build LLM Apps & AI-Agents with n8n & APIs (Udemy.com)

AI Automation is the Future.

But how does it really work?
And how can AI optimize business processes—on a whole new level, far beyond ChatGPT?
The answer: AI Agents.

This course guides you through both essential and advanced concepts in automation using AI automation, AI agents, LLMs, vector databases, Retrieval-Augmented Generation (RAG), and n8n. You'll learn how to create powerful automations, build intelligent AI agents, and seamlessly integrate them into your workflows to enhance both business and personal projects.

Additionally, you'll receive 29 downloadable JSON workflows to accelerate your learning and implementation.
