Stop Paying for RAG! Build a FREE Production-Ready RAG with n8n | Creating a RAG Agent in n8n

Most RAG tutorials on YouTube use paid tools, subscriptions, or expensive APIs.

In this video, I show how to build a *100% FREE and PRODUCTION-READY RAG (Retrieval-Augmented Generation) system* using n8n Cloud, Google Drive, Hugging Face embeddings, Qdrant Vector Database, and Google Gemini — without using OpenAI or any paid subscriptions.

I import the workflow JSON into n8n Cloud and explain the **entire system node by node**, so you can clearly understand how a real-world RAG system is built and deployed.

🔥 Why this video is different:
No paid vector databases
No OpenAI / paid LLMs
No hidden subscriptions
Fully cloud-based
Production-ready architecture
Beginner-friendly explanation

📌 What you will learn:
What RAG (Retrieval-Augmented Generation) really is
How to use Google Drive as a knowledge base
How to extract text from DOCX / PDF files
How embeddings work using Hugging Face (MiniLM)
How to store embeddings in Qdrant (FREE Vector DB)
How semantic search works
How to answer questions using Google Gemini
Full node-by-node explanation in n8n Cloud
How to build a real production-ready RAG system for FREE
