Generate weekly Reddit startup opportunity reports with Groq AI

This n8n template automatically scans 10 subreddits every Monday, filters ~1000 posts for genuine frustration signals, and delivers a structured startup opportunity report to your inbox — powered by Groq AI.

Perfect for indie hackers, product builders, and founders who want to stay on top of what people are actually begging someone to build — without spending hours manually browsing Reddit.

Good to know

- Uses Reddit's public JSON API — no Reddit account or API key required - Groq's free tier is generous enough to run this weekly at zero cost - Each run analyzes up to 1000 posts and completes in under 60 seconds

How it works

- A Schedule Trigger fires every Monday at 8AM to kick off the workflow - A Code node defines 10 target subreddits (entrepreneur, SaaS, freelance, startups, and more) - An HTTP Request node fetches the 100 newest posts from each subreddit using Reddit's public JSON endpoint - A Code node filters all posts against 27 frustration-signal keywords like "why doesn't X exist", "sick of manually", "wish there was a tool for this" - An Aggregate node merges all matched posts from all 10 subreddits into a single dataset - A Code node builds a structured AI prompt embedding all posts with specific instructions for analysis - An HTTP Request node sends the dataset to Groq's API (llama-3.3-70b-versatile) for deep analysis - A Code node wraps the AI output in a clean HTML email template - A Gmail node delivers the weekly report directly to your inbox

How to use

- Import the workflow and connect your Groq API key as an HTTP Header Auth credential - Connect your Gmail account via OAuth2 - Change the recipient email in the Gmail node to your own address - Run manually first to verify the full flow end to end, then activate the schedule
