n8n Step by Step: Build AI Agentic RAG System Like A Pro with Supabase

n8n git: https://github.com/ShenSeanChen/yt-n8... | I built an AI Agentic RAG workflow with n8n and Supabase. It is a follow-up implementation of the AI RAG System Design I launched a few weeks ago. You will see an AI Sales Automation example for customers of a car dealership asking the AI agent questions on inventory and sales policies. Should be a fun video to watch if you're into AI automation workflows and building your own Agentic RAG. Hope you'll enjoy! You can build anything. You can learn anything. 💪 Launch Full-Stack App Template: https://github.com/ShenSeanChen/launc...
