Reddit AI Digest for n8n: Weekly Email/Slack Summary

Never miss important n8n mentions—get a weekly Reddit digest in Email or Slack

This n8n workflow automatically scans Reddit for posts that may be about n8n, filters the most relevant items, and produces a clean weekly summary you can send as a single Email or Slack digest. It uses OpenAI to confirm whether a post is truly about n8n, then turns qualifying posts into concise bullet-point sentences.

What this workflow does

• Collects potential n8n posts from Reddit (candidates that might mention n8n).
• Filters for relevance: only considers posts from the last 7 days, with more than 5 upvotes, and original content.
• Verifies topic with OpenAI: classifies whether each Reddit post is actually about n8n (not just a coincidental keyword match).
• Summarises into action-friendly bullets: when a post qualifies, OpenAI generates a bullet-point sentence summary.
• Sends one weekly digest as either a single email or a Slack summary.

Important detail (post text limit)

The workflow only evaluates the first 500 characters of each Reddit post. If n8n is mentioned after that limit, the workflow may not detect the post as n8n-related.

Use cases

• SaaS operators who want lightweight social listening for n8n community feedback.
• Automation engineers tracking common n8n integration questions and troubleshooting patterns.
• Product teams monitoring what users discuss in Reddit over time—summarised weekly without manual searching.

Technical details

• Integrations / nodes: Reddit, OpenAI, and digest delivery via Email or Slack.
• Workflow logic: if, set, merge, OpenAI for classification + summarisation, plus sticky note documentation.

Designed for n8n automation workflow users who want credible, OpenAI-validated Reddit insights delivered on a schedule.
