This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

🤖 AI-Powered Document QA System using Webhook, Pinecone + OpenAI + n8n

This project demonstrates how to build a Retrieval-Augmented Generation (RAG) system using n8n, and create a simple Question Answer system using Webhook to connect with User Interface (created using Lovable):

🧾 Downloads the pdf file format documents from Google Drive (contract document, user manual, HR policy document etc...)

📚 Converts them into vector embeddings using OpenAI

🔍 Stores and searches them in Pinecone Vector DB

💬 Allows natural language querying of contracts using AI Agents
