Knockoff - Amazon Brand Filter 作者: Ordinary Systems

Amazon is flooded with trademark-squat "brands": random strings like SZHLUX, HORUSDY, and LATTOOK, registered at the USPTO purely to unlock Amazon Brand Registry. They sell commodity goods with no company, no warranty, and no reputation behind them.

Knockoff appraises every listing's brand right in your search results and hides, dims, or labels the junk, so what's left is brands with a reputation to lose.

HOW IT WORKS
• Every brand is checked against a curated register of ~5,500 established brands, refreshed daily.
• Unknown names are scored on the linguistic signature of pseudo-brands: all-caps squat-length strings, vanishing vowels, unpronounceable consonant runs.
• Your allowlist and blocklist override everything.

FEATURES
• Hide, dim, or label flagged listings, with a one-click reveal.
• Optionally hide Amazon's paid "Sponsored" listings too (off by default).
• Three filter levels: Relaxed, Standard, Strict.
• Trust or block any brand in one click, right from the results.
• One-click misclassification reporting that improves the shared lists for everyone.

PRIVATE BY DESIGN
