Parallax: Compare AI Models

About this app

Stop copying the same prompt into different AI apps. Parallax sends your question to ChatGPT, Claude, Gemini, and Grok simultaneously — then shows you where they agree, where they differ, and why it matters. WHY PARALLAX? Every AI model has blind spots. ChatGPT reasons differently than Claude. Gemini sees things Grok misses. The truth and the full picture is usually in the overlap. Parallax finds that overlap for you. FEATURES Compare AI Models at Once Ask one question. Receive responses from ChatGPT, Claude, Gemini, Grok, and more all running in parallel. No switching tabs. No copying prompts. Consensus Summary See what all models agree on. Parallax synthesizes common patterns across every response so you can find the signal in the noise. Divergence Analysis Find exactly where AI models disagree and what those differences reveal about your question. Useful for research, decision-making, and stress-testing ideas. Side-by-Side Layout A clean, structured interface built for comparison not conversation. Read every AI's take without losing context. Favorites & History Save queries that matter.
