  ModMind - Agentic Reddit Security Operations

💡 Inspiration

Reddit communities face constant threats from toxic content, spam, and harmful posts. Security teams need real-time visibility into these threats. I built ModMind to bridge AI-powered content moderation with enterprise security operations using Splunk.

🛡️ What it does

ModMind is an AI-powered Reddit Security Operations platform that:

• Fetches posts from any subreddit in real-time
• Analyzes content using Gemini AI for toxicity scoring and sentiment
• Suggests mod actions — approve, remove, flag, or monitor
• Logs every decision to Splunk as a security event via HEC
• Enables threat hunting through Splunk dashboards and SPL queries

🔨 How I built it

• Frontend: React + Tailwind CSS
• Backend: Python FastAPI
• AI: Google Gemini API (gemini-flash-latest)
• Security Analytics: Splunk Cloud + HTTP Event Collector
• Deployment: Vercel + Render

🚧 Challenges I faced

• SSL certificate issues when sending events to Splunk HEC
• Reddit API rate limiting requiring fallback mock data
• Designing the right event schema for Splunk threat analytics

📚 What I learned
