🧠 Reddit MVP Generator – Auto-Generate Startup Ideas from Real User Pain Points
The Reddit MVP Generator is a fully automated business idea mining system built in n8n. It scans trending posts and user comments on Reddit to identify real-world pain points and uses an AI-powered chain to generate detailed, structured MVP business ideas—including industry, business type, revenue potential, and startup cost estimates.

🚀 Key Features
Live Reddit Scraper: Select from a curated list of entrepreneur and business subreddits (e.g., r/smallbusiness, r/entrepreneur, r/marketing) to fetch top trending posts.

Comment Analysis: Pulls Reddit comments and flattens threads to extract community pain points.

AI Business Generator: Uses OpenRouter-compatible LLMs (like GPT-4o-mini or Gemini Flash) to analyze post content and comments. Outputs are structured JSON objects with MVP ideas.

Zero Duplicate Analysis: Automatically deduplicates previously analyzed Reddit posts using a dynamic blocklist.

Excel Integration: Saves each MVP idea directly into your Microsoft Excel 365 sheet, organized by MVP, Industry, Pain Point, Startup Costs, and Revenue potential.
