⚡ AI Arbitrage — Multi-LLM Response Comparator

Compare responses from GPT-4, Claude, Gemini & Mistral side-by-side. Get the best answer, every time.

🎯 What is AI Arbitrage?

AI Arbitrage is a Chrome extension that automatically queries multiple AI models when you ask a question on ChatGPT, Claude, Gemini, or Mistral. It displays all responses side-by-side so you can:

• 🏆 Find the best answer — See which model gives the most comprehensive response
• 🚀 Compare speed — Know which model responds fastest
• 💰 Track costs — See how much each query costs you
• 🎯 Check consensus — See if models agree or contradict each other

✨ Features

• Parallel API Calls — All models are queried simultaneously for speed
• Smart Analysis — Automatic detection of fastest, cheapest, and most detailed response
• Consensus Detection — Highlights when models agree or disagree
• Cost Tracking — Real-time cost calculation per query
• Premium UI — Glassmorphic, dark-mode design
• Keyboard Shortcuts — Ctrl+Shift+A to trigger comparison
• 100% Local — API keys stored locally, never sent anywhere except official APIs
