Automate Morning Brew–style Reddit Digests and Publish to DEV using AI

This workflow contains community nodes that are only compatible with the self-hosted version of n8n.

Who’s it for

Community managers, content marketers, and builders who want a daily, skimmable update from a subreddit—automatically summarized, formatted, and cross-posted to DEV Community.

Here is a Link to video hackathon detailing this build.

What it does

• Collects fresh posts from a subreddit (seeded via RSS).
• Uses the Bright Data node to batch-scrape each post for richer fields (upvotes, comment count, comments).
• Flattens comments/replies with JMESPath and trims payload size.
• Summarizes into a Morning Brew–style brief (Top Stories, Quick Hits, Community Q&A, Comment Spotlight).
• Converts to clean Markdown and publishes to DEV with HTTP Request.
• Optional: emails the same digest via Gmail.

How to set up

1. Trigger: Start with Manual Trigger; swap to Cron (daily) when ready.
2. RSS → URLs: Set the subreddit RSS of your choice, just add .rss to the end of the subreddit URL.
3. Update AI Prompt to fit your needs

Requirements

• DEV Community API key.
• Bright Data account + the Bright Data api key Found Here.
• Optional: LLM provider credentials (OpenAI, Gemini).

How to customize

• Swap DEV publishing for email/Slack; or post both.
• Add more subreddits and dedupe by URL.

Best practices

• No hardcoded API keys—use credentials.
• Pin long-running outputs while building to save credits.
• Only collect publicly available data with Bright Data.
