This workflow allows you to ask questions about a PDF document. The answers are provided by an AI model of your choice, and the answer includes a citation pointing to the information it used.

You can use n8n’s built-in chat interface to ask the questions, or you could customize this workflow to use another one (e.g. Slack, Teams, etc.).

Example:
The workflow is set up with the Bitcoin whitepaper. So you could ask things like:Question: “Which email provider does the creator of Bitcoin use?“Answer: “GMX [Bitcoin whitepaper.pdf, lines 1-35]”

Requirements:
– A Pinecone account (they have a free tier at the time of writing that is easily enough for this workflow)
– Access to a large language model (e.g. an OpenAI account)Customizing this workflow:
The workflow only reads in one document, but you could customize it to read in all the documents in a folder (or more).

The workflow is set up to use GPT 3.5, but you could swap that out for any other model (including self-hosted ones).
