WhileAI is a Chrome extension that lets you test and compare responses from multiple AI models simultaneously. Send a single prompt to ChatGPT, Claude, Perplexity, Gemini, and DeepSeek in separate tabs, and see how each model responds with built-in timing for performance tracking.
Perfect for developers and researchers who want to evaluate AI model behavior, compare answer quality, and measure response speed—all while keeping your data local in your browser. Nothing leaves your device.
