Automated Notion Comment Summarization Workflow

This n8n workflow automates the process of extracting comments from Notion pages, generating concise AI-based summaries of email-like conversations, and updating the pages with these summaries along with the last execution timestamp. It is triggered every hour but can be adapted to run via Notion webhooks for real-time updates. The workflow begins by defining variables for your Notion database and credentials, then schedules or triggers the fetch of all pages within the database. It filters pages to include only those with new comments since the last run, extracts the comments, and sends them to an AI language model (such as Google Gemini or others) for summarization. The generated summary is then written back to the relevant Notion page, alongside updating the last execution date. This system is ideal for streamlining communication review, summarizing lengthy email threads, or businesses that need automated insights from ongoing discussions within Notion.
