Here’s a new workflow I recorded: a clean RAG setup in n8n that prioritizes input quality.
What’s inside
• Drive → filter PDFs → extract text
• AI Agent creates summary, keywords, search terms per chunk
• Merge text + metadata → Pinecone
• Query with GPT-4.1 and run an 8-question evaluation set
• Results + ideas to improve without a re-ranker Why it matters (client angle)
Clients don’t pay for “chat with docs”—they pay for correct answers.
Better ingestion + metadata = higher accuracy and fewer hallucinations.
Tools used n8n, Google Drive, Pinecone, OpenAI GPT-4.1, text-embedding-3-large
