BuyShield – Product Safety & Review Intelligence by Helpful Extensions

BuyShield analyzes Amazon product pages to tell you what sellers don't want you to know — before you buy. What BuyShield checks: • Fake review detection — flags inflated or incentivized reviews • AI-generated review % — identifies machine-written content • Review quality drop — alerts you if ratings fell in the last 30 days • Verified purchase ratio — how many reviews are actually verified • Seller trust signals — fulfillment type, listing age, BSR rank How it works: Navigate to any Amazon product page and click the BuyShield icon. Within seconds you get a Trust Score out of 100, a Buy / Wait / Skip recommendation powered by Gemini AI, and a breakdown of every risk signal detected. Why BuyShield vs. competitors: Most review checkers only grade the reviews. BuyShield combines heuristic analysis with live AI to surface quality trends, conversion signals, and fake review patterns that tools like Fakespot miss entirely.
