My Reddit AI Intelligence Vault (N8N Workflows) 🤖🚀
- 12/08/2025
Description
Paul demonstrates how he transformed Reddit into an AI-powered research assistant for Obsidian using n8n workflows. The video walks through two automation setups: a basic Reddit analysis system that gathers insights from subreddits and an advanced version that generates AI-enhanced summaries, productivity suggestions, and formatted Obsidian markdown reports—all fully automated.
Best Ideas
Automate Reddit Research: Use n8n to scrape top weekly posts from a subreddit, filter them, and analyze their content automatically.
AI-Driven Insights: Integrate Google Gemini to extract trends, insights, and actionable knowledge from Reddit posts.
Dual Output System: Deliver results directly to Discord (for instant summaries) and Obsidian (for permanent research storage).
Local REST API Integration: Connect Obsidian via its local REST API plugin to enable secure automated note creation.
Self-Hosted Privacy & Scalability: Host n8n in a Docker container within a Proxmox home lab and expose it safely via a Cloudflare tunnel—achieving unlimited workflows without SaaS limitations.
Advanced AI Enhancement: The second workflow uses AI to identify high-value posts, assess their productivity potential, and generate improvement suggestions.
Reddit Intelligence Vault: All workflows, setup guides, and sample data are packaged into an Obsidian vault for fast implementation.
