Self-Hosted AI Knowledge Bot in n8n — Answer from your docs (RAG) and Save It to Notion
Every time a new document is added to your drive, this workflow hands it to OpenAI, which retrieves the right passage from your knowledge base and answers with sources. You get an AI assistant that answers from your own docs without lifting a finger.

Frequently asked questions
Can I trust the AI to get the answer right?
The prompt is tightly scoped to one job and you can add a human-approval step in n8n before anything is sent or published. Start with review-mode for a week, and once you trust the output, switch it to fully automatic.
Does this need n8n Cloud or can I self-host?
Either works. The workflow is a standard n8n export, so you can run it on n8n Cloud or on your own self-hosted instance — you only connect your own app credentials.
How do I import the workflow into n8n?
Download the JSON, then in n8n open a new workflow, choose ⋯ → Import from file, and select it. Every trigger, node and connection appears on the canvas; you just add your credentials and activate it.
