Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

reaction_check | Review and stress-test launch messaging, landing pages, product announcements, pricing pages, changelogs, app-store listings, and marketing emails before publication. LaunchCheck evaluates copy through eight audience lenses, surfaces positioning and conversion friction, flags claims needing evidence, predicts likely reader questions, recommends concrete changes, and returns a fact-preserving rewrite. Requires $0.50 via x402 on Base. |
