Knockoff: A Free Browser Extension to Filter Fake Brands on Amazon

Amazon Without the Knockoffs

I built Knockoff, a free, privacy-first browser extension that filters out trademark-squatting pseudo-brands like SZHLUX and HORUSDY from your Amazon search results. By running entirely locally in your browser with no accounts or tracking, it highlights established brands like Casper and Carhartt while dimming or hiding suspicious listings. You can customize the strictness, hide sponsored ads, and contribute to a community-maintained list of real brands to keep your shopping experience clean.
