RAG-powered document chat with Google Drive, OpenAI, and Pinecone Assistant

Description

Try it out

This n8n workflow template lets you chat with your Google Drive documents (.docx, .json, .md, .txt, .pdf) using OpenAI and Pinecone Assistant. It retrieves relevant context from your files in real time so you can get accurate, context-aware answers about your proprietary data—without the need to train your own LLM.

What is Pinecone Assistant?

Pinecone Assistant allows you to build production-grade chat and agent-based applications quickly. It abstracts the complexities of implementing retrieval-augmented (RAG) systems by managing the chunking, embedding, storage, query planning, vector search, model orchestration, reranking for you.

Prerequisites

A Pinecone account
A GCP project with Google Drive API enabled and configured
An Open AI account and API key

Setup

Create a Pinecone Assistant named n8n-assistant in the Pinecone Console here
Setup your Google Drive OAuth2 API credential in n8n
In the File added node -> Credential to connect with, select Create new credential
Set the Client ID and Client Secret from the values generated in the prerequisites
Set the OAuth Redirect URL from the n8n credential in the Google Cloud Console (instructions)
Name this credential Google Drive account so that other nodes reference it
Use the Connect to Pinecone button to authenticate to Pinecone or if you self-host n8n, create a Pinecone credential and add your Pinecone API key directly
Select your Assistant Name in each of the Pinecone Assistant nodes
Setup the Open AI credential in n8n
In the OpenAI Chat Model node -> Credential to connect with, select Create new credential
Set the API Key field to your OpenAI API key
Add your files to a Drive folder named n8n-pinecone-demo in the root of your My Drive
If you use a different folder name, you'll need to update the Google Drive triggers to reflect that change
Activate the workflow or test it with a manual execution to ingest the documents
Chat with your docs!

Ideas for customizing this workflow

Customize the System Message on the AI Agent node to your use case to indicate what kind of knowledge is stored in Pinecone Assistant
Change the Top K and/or Snippet Size values to help manage token consumption by adding the Top K and/or Snippet Size parameters to Get context from Assistant node
