In this detailed tutorial, Nate Herk demonstrates a robust RAG system built on n8n that integrates Supabase and Postgres for dynamic document management. The workflow monitors a Google Drive folder for file creations and updates, automatically converting file types (e.g., Google Docs to text, PDF processing) and extracting metadata for vector database uploads. With built-in versioning and AI agent interaction, this automation streamlines data consistency and retrieval. Free template available via the Skool community.
