Knockoff - Amazon Brand Filter wot 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.

Featured in Fast Company, Gizmodo, 404 Media, PC Gamer, Yahoo, and Lifehacker.

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
The brand appraisal runs locally in your browser. No accounts, no profiles, nothing tied to you. Two features send data. Both are on by default, and both can be switched off: seller country sends seller IDs, so it can show where a seller is based; and Help pick US alternatives sends the product pages you open, so we know which products people want US alternatives for. A stored row records that a product was viewed N times, never who viewed it. Reports stay opt-in and anonymous. Full detail: knockoff.co/privacy
