Discord to Gmail Article Digest (OpenAI + Google Sheets) | n8n

Get an AI-powered article digest from your Discord—then email it automatically with n8n.

This Discord to Gmail Article Digest (OpenAI + Google Sheets) workflow monitors a Discord channel for shared links, uses OpenAI (gpt-4o-mini) to summarize each article, stores results in Google Sheets, and sends a formatted email digest via Gmail when someone types !digest.

What this workflow does

• Runs every 15 minutes to fetch recent messages from a specified Discord channel.
• Ignores bot messages, extracts URLs from user messages, and detects the !digest command while tracking the last processed command ID.
• For each new URL, reads the Google Sheets “articles” tab and filters out URLs already saved or duplicated in the current run.
• Downloads each new article’s HTML and sends it to OpenAI (gpt-4o-mini) to generate:
  • Title
  • Three-sentence summary
  • Category
  • Key takeaway
• Appends the results to Google Sheets and posts ingestion success (or error notice) back to Discord.
• When a new !digest command is detected, it pulls unsent rows, builds an HTML digest, and emails it via Gmail.
• After successful email delivery, the workflow marks those rows as sent in Google Sheets and confirms back to Discord.

Use cases

• Turn community-shared links into an automated newsletter for SaaS teams.
• Keep operators informed by emailing a curated article digest whenever !digest is requested.
• Maintain a searchable archive of summarized links in Google Sheets, deduplicated by URL.

Technical details

• Discord: monitor channel messages and post processing confirmations

Perfect for n8n automation engineers and SaaS operators who want an end-to-end OpenAI + Google Sheets workflow that starts from Discord and ends in a Gmail digest.
