Automatically document and backup N8N workflows

Automatically backs up your workflows to Github and generates documentation in a Notion database.

• Weekly run, uses the "internal-infra" tag to look for new or recently modified workflows
• Uses a Notion database page to hold the workflow summary, last updated date, and a link to the workflow
• Uses OpenAI's 4o-mini to generate a summarization of what the workflow does
• Stores a backup of the workflow in GitHub (recommend a private repo)
• Sends notification to Slack channel for new or updated workflows

Who is this for

• Anyone seeking backup of their most important workflows
• Anyone seeking version control for their most important workflows

• OpenAI: You will need an OpenAI credential, unless you intend on rewiring this with your AI of choice (ollama, openrouter, etc.)
