n8n Reddit Trending Threads to LinkedIn, Facebook & Bluesky

Turn Reddit’s hottest discussions into daily LinkedIn, Facebook, and Bluesky posts—automatically

This n8n workflow finds the most talked-about “rising” thread from your chosen subreddit each day, uses OpenAI to create original platform-specific copy, publishes via PostWire, and logs everything to Google Sheets with Gmail alerts when anything goes wrong.

What this workflow does

• Runs daily at 8:00 to load your feed settings and fetch up to 25 rising posts from a specified subreddit using Reddit.
• Filters for real discussions: it requires minimum upvotes and comments, excludes stickied and NSFW threads, and skips threads already processed in previous runs.
• Chooses the top conversation by sorting remaining threads by comment count and selecting the single most discussed thread.
• Generates original posts with OpenAI: it sends the thread details to OpenAI to create an original angle and tailored copy for LinkedIn, Facebook, and Bluesky.
• Publishes through PostWire and appends a source link back to the Reddit thread.
• Logs results in Google Sheets: appends a “posted” row when all networks succeed.
• Handles failures automatically: if any network fails, it appends a “needs fix/partly posted” row and emails detailed failure info plus any successful post links via Gmail.

Use cases

• SaaS operators and founders who want consistent social posting driven by real community conversations.
• Automation engineers building a reliable “social content from Reddit” publishing pipeline in n8n.
• Teams that want auditability (Google Sheets) and alerts (Gmail) for multi-network publishing.

Technical details

• Integrations/credentials: Reddit OAuth2, OpenAI API key, PostWire API credential, Gmail, Google Sheets.
