What this workflow does

This AI workflow has 17 nodes and runs when someone submits an n8n form (“Paper → Teaching Pack”). Along the way it connects Mistral Cloud Chat Model, Gmail and Qwen Cloud Chat Model. It also calls gotenberg:3000 over HTTP.

How it runs

Trigger: When someone submits an n8n form (“Paper → Teaching Pack”).

1. Normalise upload (Code): runs custom JavaScript code
2. Extract PDF text (Extract from File): extracts data from a file (pdf)
3. Enough text? (If): checks a condition and branches into true / false
4. Prepare input (Edit Fields (Set)): sets 4 fields: paperText, sessionMinutes, studentLevel…
5. Couldn't read that PDF (n8n Form): shows the next form page
6. Teaching pack agent (AI Agent): runs an AI agent, with model: Qwen Cloud Chat Model, Fallback: Mistral Large; output parser: Teaching pack schema
7. Build report HTML (Code): runs custom JavaScript code
8. HTML to file (Convert to File): converts data to a file (to text)
9. Render PDF (Gotenberg) (HTTP Request): calls gotenberg:3000 (POST)
10. Name the PDF (Code): runs custom JavaScript code

…plus 2 more steps. See the full node list below.

From the author

Quick overview This workflow collects a research paper PDF via an n8n Form, uses an AI agent (with schema validation) to generate a seminar-ready teaching pack and slide plan, renders it to a PDF with Gotenberg, and emails the finished pack to the requester…
