RAG Documentation Expert Bot with Gemini & Supabase

This advanced n8n workflow creates a Retrieval-Augmented Generation (RAG) pipeline to transform an AI into a domain-specific expert, exemplified by indexing the n8n documentation. It scrapes web pages, chunks content, generates embeddings, and stores them in a Supabase vector database for precise retrieval. The chatbot then queries this knowledge base to provide factual, grounded responses using only relevant document chunks fed to Gemini, eliminating hallucinations and ensuring accuracy. Part
