Document Q&A system with OpenAI GPT, Pinecone Vector DB & Google Drive integration
Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 24 nodes and runs manually, when you click “Execute workflow” (plus 2 other triggers). Along the way it connects Google Drive, Pinecone Vector Store, Embeddings OpenAI and OpenAI Chat Model and 1 more.
How it runs
Trigger: Manually, when you click “Execute workflow” (plus 2 other triggers).
- Google Drive: work with file folder
- AI Agent: runs an AI agent, with model: OpenAI Chat Model; 1 tool (Answer questions with a vector store); memory: Simple Memory
- AI Agent: runs an AI agent, with model: OpenAI Chat Model; 1 tool (Answer questions with a vector store); memory: Simple Memory
- Google Drive: download
- Respond to Webhook: sends the response back to the webhook caller
- Pinecone Vector Store: stores documents in the Pinecone vector store, with embeddings: Embeddings OpenAI; document loader: Default Data Loader
Services it uses
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
