Knockoff - Amazon & Etsy Shopping Filter

Filters pseudo-brand junk out of Amazon, checks if Etsy listings are really handmade, hides sponsored listings.

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. Etsy has its own version of the problem: mass-produced catalog goods dressed up as handmade, sold by shops that never made anything. Knockoff checks what you're actually buying, right in your search results. On Amazon it filters the pseudo-brand junk out; on Etsy it tags listings whose handmade story doesn't hold up. Featured in Fast Company, Gizmodo, 404 Media, PC Gamer, Yahoo, and Lifehacker. ON AMAZON • Every listing's brand is appraised right in your results, and the junk is hidden, dimmed, or labeled, so what's left is brands with a reputation to lose. • Brands are 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. • Three filter levels: Relaxed, Standard, Strict. Your allowlist and blocklist override everything. • Trust or block any brand in one click, right from the results, with one-click misclassification reporting that improves the shared lists for everyone. • Optionally hide Amazon's paid "Sponsored" listings too (off by default). • See where each seller is based, and hide listings from countries you pick. ON ETSY • A listing claims a maker. Knockoff reads that claim against the shop's own facts: its age, its sales pace, where orders really ship from, and whether the photos turn up on mass-market catalog listings. • When the story doesn't hold up, the listing gets a tag in your search results, and opening it shows why. Nothing is hidden or reordered, and a page with no tags means nothing looked off. • Etsy checking is something you turn on. One switch in settings covers Etsy and every shopping site we add next; Walmart and Shopify stores are coming. PRIVATE BY DESIGN Knockoff runs on Amazon, and on Etsy once you turn marketplace checks on. It reads only the pages of the shopping sites it supports, and carries no code for anywhere else. The brand appraisal runs locally in your browser. No accounts, nto 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 knownt US alternatives for and can spot new junk brands on marketplaces the filter can't read yet. With Etsy turned on, the same switch also sendsblic signals, so independent sightings can corroborate or clear it. A stored row records that a product was viewed N times, never who viewedrches, your orders, or anything you type into a page. Reports stay opt-in and anonymous. Full detail: knockoff.co/privacy Free.
