Hello Product Hunt! 👋 I built MultiBrain because I was tired of paying $100+/month for "Pro" access to 5 different AI models just to compare their logic. As a DevOps engineer, I value efficiency and hate friction. MultiBrain.chat is my solution to "subscription fatigue." It’s a unified interface where you can chat with GPT-5.2, Claude 4.5, Gemini 3, and others—all for a flat $8/month. What makes it different: The Arbitrage: Use all top-tier models for the price of two cups of coffee. Real-time Benchmarking: Send one prompt to multiple LLMs and compare answers side-by-side. Universal Context: Set your global instructions and memory once; they persist across every model you talk to. Minimalist UI: No bloat. Just the models and your workflow. I’m here all day to answer technical questions about our architecture or how we handle context. I'd love your critical feedback on the UI! Let’s chat, Saif
