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 is a Safari extension that appraises every listing's brand right in your Amazon search results and hides, dims, or labels the junk, so what's left is brands with a reputation to lose. Works on iPhone, iPad, and Mac. Featured in Fast Company, Gizmodo, 404 Media, PC Gamer, Yahoo, and Lifehacker. HOW IT WORKS • Every brand is checked against a curated register of 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 Knockoff works only on Amazon pages. It has no access to your browsing history and never sees the other sites you visit. The brand appraisal runs locally on your device. No accounts, no profiles, nothing tied to you. Two features send data. Both are on by default, and both can be switched off in settings: 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. Never sent: your searches, your orders, or anything you type into a page. Reports stay opt-in and anonymous. Full detail: knockoff.co/privacy Free. Works on 23 Amazon marketplaces worldwide, including amazon.com, .ca, .co.uk, .de, .fr, .co.jp, .in, and .com.au. To turn it on: enable Knockoff in Safari's Extensions settings and allow it on Amazon. Search as usual, and the junk brands drop out.
