n8n Template Docs & Assets Generator (OpenAI, Notion, Email)

Turn an n8n export into a ready-to-publish template package—automatically

The n8n Template Docs & Assets Generator (OpenAI, Notion, Email) workflow prepares your exported n8n workflow for distribution by sanitizing secrets, generating documentation and Gumroad delivery metadata, creating thumbnails/cover images with OpenAI, and publishing structured docs to Notion.

What this workflow does

• Start from your exported workflow JSON: Upload an n8n workflow export via the Upload workflow form trigger.
• Send notifications: The Email configuration node sets sender/recipient email addresses for delivery updates.
• Sanitize sensitive data: Scan and redact workflow secrets removes secrets from the uploaded JSON so you can publish safely.
• Extract metadata for documentation: Analyze uploaded JSON extracts details needed to produce consistent docs.
• Reference the latest repository README: Read GitHub repository README fetches README content to inform the generated documentation.
• Generate deliverables with AI: AI nodes create unified documentation (AI - Unified documentation), Gumroad delivery page content (AI - Gumroad delivery and metadata), and `AI - Visual prompts` for images.
• Create visual assets: Visual prompts are used by OpenAI Image Generation nodes to generate thumbnail and cover images.
• Publish Notion documentation: The workflow detects required external services and generates detailed multi-page Notion docs, then uses Notion API nodes to create and populate pages in your configured workspace.
• Improve workflow readability: Sticky notes are generated or preserved and nodes are aligned for easier review.

Use cases

• Package and publish n8n templates to Gumroad with consistent docs, images, and metadata.
• Convert internal n8n automations into shareable templates—without leaking secrets.
• Automatically maintain structured Notion documentation for each template release.
