n8n

This workflow enables the creation of an AI-powered assistant that can answer questions based on your company's documents. It leverages RAG to search and retrieve relevant information from a Supabase vector store, updated through Google Drive. The assistant supports both voice and text input, transcribing voice messages with OpenAI Whisper. Two additional workflows ensure that any new or updated documents in Google Drive are processed and synchronized with the Supabase vector database, maintaining an up-to-date knowledge base.
