19 min • 30 juli 2025

Standard AI is like a brilliant intern who knows nothing about your business. 🧠 We're revealing the complete beginner's guide to building a RAG agent with a custom brain in just 20 minutes, no code required.

We’ll talk about:

A step-by-step, no-code guide to building a fully functional RAG agent using n8n and Supabase.
The "Librarian and Scholar" analogy: the two-part system of a backend pipeline that stocks the knowledge base and a front-end agent that answers questions.
A detailed walkthrough of the Supabase setup, including the exact SQL script that turns a standard database into a powerful vector database.
How to give your RAG agent conversational memory and use "Session IDs" to enable personalized conversations for thousands of users.
Plus, a full breakdown of the "AI Golf Caddie" case study and a crucial guide to setting up OpenAI API keys for cost control.
