Only for iPhone
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Ask ChatGPT, Claude, Gemini & Grok the same question. See where they all agree and exactly where they don't. One app. Four AIs.
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.
