Answer WhatsApp questions from PDF documents using RAG, Google Drive and Pinecone

Good to know:

This workflow creates a WhatsApp chatbot that answers questions using your own PDFs through RAG (Retrieval-Augmented Generation). Every time you upload a document to Google Drive, it is processed into embeddings and stored in Pinecone—allowing the bot to respond with accurate, context-aware answers directly on WhatsApp.

Who is this for?

- Anyone building a custom WhatsApp chatbot. - Businesses wanting a private knowledge based assistant

- Teams that want their documents to be searchable via chat

- Creators/coaches who want automated Q&A from their PDFs

- Developers who want a no-code RAG pipeline using n8n
