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

Trigger: Start with Manual Trigger; swap to Cron (daily) when ready. RSS → URLs: Set the subreddit RSS of your choice, just add .rss to the end of the subreddit URL. 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.
