RebutAI - AI-powered rebuttals. Wallet login. No subscriptions.

RebutAI helps you craft sharp, well-reasoned rebuttals to criticism, bad reviews, or online arguments — in seconds. Paste what was said, get a polished, articulate response you can actually use. What makes it different: no email, no password, no subscription. You connect your wallet, pay on-chain (USDT), and that's it. Identity is your wallet address. Built on the Sovereign stack (svgn.org), where ownership replaces accounts.
