GoBuy uses a Wilson confidence interval to weight statistical significance, a Bayesian Beta model for verified-purchase share, compound penalty scoring for suspicious review patterns, and an AI fingerprint detector to flag template-written or AI-generated reviews. The methodology is fully published at gobuy.ai/methodology — not a black box. PRIVACY FIRST ───────────── GoBuy only activates on product pages.
