Boost Team Efficiency with n8n's RAG Chatbot Workflow

Transform your internal knowledge base into an intelligent, searchable AI assistant that delivers instant answers to your team's questions. This n8n RAG (Retrieval-Augmented Generation) chatbot workflow combines OpenAI's powerful language models with Supabase Vector Store to create a document-based Q&A system that eliminates time-consuming manual searches through company files.

What This Workflow Does

The workflow operates through two integrated processes:

Document Ingestion: Automatically receives internal document content via webhook, normalizes and validates the data, splits documents into optimized chunks, generates embeddings using OpenAI Embeddings, and stores everything in Supabase Vector Store for lightning-fast retrieval.

AI-Powered Q&A Chat: Accepts user questions through n8n Chat Trigger, intelligently retrieves relevant document chunks from your vector database, leverages OpenAI Chat Model to generate accurate, contextual answers, and delivers structured responses instantly.

• Employee Onboarding: Provide new hires instant access to policies, procedures, and guidelines
• Sales Playbook Search: Help sales teams quickly find relevant strategies and talking points
