Make your AI Agents 10x Smarter with GraphRAG (n8n)

👉 Get our State-of-the-Art n8n RAG System and learn how to customize it, in our community https://www.theaiautomators.com/?utm_...

In this video, I dive deep into how you can transform your AI agents using Knowledge Graphs, combined with Retrieval Augmented Generation (GraphRAG).

Traditional AI search often misses context and relationships between data, but with this system, your AI gets a rich, structured understanding of your documents — delivering smarter, more accurate, and context-aware responses.
