CPAR — Cross-Provider Adversarial Review

CPAR runs a panel of 4 AI reviewers (Grok, Gemini, ChatGPT, Claude) on your document in parallel — each from a different provider, each with real-time web search, none seeing the others' reviews. Claude synthesizes the signals each round until the panel converges.

Paste any claim, idea, or draft. Press Start Round 1. Run 2–4 rounds. Export the full session log when done.
