Inspiration

X.com faces scams, impersonators, and misinformation. GrokGuard uses agentic AI to protect users in real time.

What it does

Real-time X.com feed scanner using Grok AI. Multi-agent system (Prosecutor, Defender, Arbiter) debates each post to detect scams, impersonators, and misinformation. Collapses dangerous posts, labels misinformation, and provides a live dashboard.

How we built it

  • Chrome Extension (Manifest V3) + Grok API
  • TypeScript agent orchestration (custom, no frameworks)
  • Express.js API server + Next.js dashboard
  • Real-time DOM monitoring for feed analysis

Challenges we ran into

  • False positives on legitimate accounts → fixed with multi-factor legitimacy scoring
  • Real-time performance → hybrid approach: instant analyzer for feed, full debate for profiles
  • Extension context invalidation → heartbeat checks and state recovery

Accomplishments that we're proud of

  • Truly agentic: autonomous investigation + multi-turn debate
  • Zero false positives on verified accounts
  • Real-time feed protection with instant AI analysis

What we learned

  • Agentic AI needs clear agent roles and debate structure
  • Hybrid models: fast for feed, reasoning for deep analysis
  • Source credibility is critical for fact-checking

What's next for GrokGuard

  • Human-in-the-loop learning from feedback
  • Supabase integration for persistent analytics
  • Web search integration for advanced fact-checking
  • Mobile browser support
