WhatsApp RAG Chatbot with Supabase, Gemini & OpenAI Embeddings

Build a WhatsApp AI chatbot using RAG with Supabase storage, OpenAI embeddings for semantic search, and Gemini 2.5 Flash for responses. Handles queries and document uploads in real-time.

This n8n workflow creates a powerful WhatsApp-based RAG (Retrieval-Augmented Generation) chatbot. It triggers on incoming WhatsApp messages via webhook, checks if it's a query or document upload, processes files by extracting text, generating OpenAI embeddings, and storing them in Supabase for vector search. For queries, it embeds the user input, retrieves relevant documents from Supabase, and uses Gemini 2.5 Flash LLM to generate contextual, accurate responses sent back instantly to WhatsApp.
