⚡ 573 views · 🔬 Document Extraction & Analysis
Description
What it does
This template automatically generates a professional, structured title for newly-ingested Paperless-ngx documents using AI (OpenAI GPT), then removes a processing tag to mark the document as handled.
How it works
- A webhook fires when a document needs titling (e.g., from a Paperless post-consumption script)
- The document URL is validated, then the OCR text is fetched from the Paperless API
- All PII is scrubbed from the text using n8n’s Guardrails node before sending to AI
- GPT generates a title using the format:
[YYYY-MM-DD] - [Document Type] - [Subject] - The specified processing tag is looked up and removed, then the document is updated
Requirements
- An AI provider account, such as OpenAI, Anthropic, Gemini. As configured the template uses OpenAI, but any model should work.
- A running Paperless-ngx instance that has network accessibility to your n8n server
How to use
Needs to be set up in conjunction with a running Paperless-ngx instance. See Paperless-ngx instructions here
Customization
- Edit the system message in the AI Agent node (Generate Document Name) to change the document naming convention and other guidelines
- Change the workflows on your Paperless-ngx instance to suit different needs.
