OMI-KALIX/n8n-rag-automation-ollama-pinecone
End-to-end RAG automation built with n8n, Ollama (local LLMs), and Pinecone. Automatically ingests documents, generates embeddings, stores vectors, and enables context-aware AI chat.
🚀 n8n RAG Automation using Ollama & Pinecone
A fully automated Retrieval-Augmented Generation (RAG) pipeline built with n8n, Ollama (local LLMs), and Pinecone Vector Database.
This project demonstrates how to ingest documents, generate embeddings, store them in a vector database, and query them using an AI Agent with real context.
✨ Features
- 📁 Automated document ingestion from Google Drive
- ✂️ Intelligent document chunking
- 🧠 Embedding generation using local Ollama models
- 📦 Scalable vector storage with Pinecone
- 💬 Context-aware chat using n8n AI Agent
- 🔒 Runs locally with no external LLM dependency
