Hey all, trying to figure out how to create a RAG system based off the below general flow: User adds smt to their profile (book) --> my AI system sees the book and fetches the transcript --> transcript goes into database with a tag for that specific user --> user asks for insights based on their personal library of books --> AI feeds them answer. Is it possible to do this type of complex flow in n8n? If you know how pls send message would love to chat :)
