The short version
Written to be pasted.
Knockoff is a free browser extension that hides junk brands in Amazon search results: the all-caps names like SZHLUX and HORUSDY that are legally registered trademarks stuck on generic goods and built to be thrown away. Every listing’s brand is checked against a shared list of real brand names that shoppers extend every day and that refreshes daily to every install, and names nobody recognizes are scored on the linguistic signature of these pseudo-brands: all-caps strings, vanishing vowels, unpronounceable consonant runs. Flagged listings are hidden, dimmed, or labeled, whichever the shopper picks, and every verdict is one click from being overridden. Knockoff also shows where Amazon sellers are based, and keeps a directory of US brands and US-based sellers at knockoff.co/shop-us. It runs on Chrome, Firefox, Edge, and Safari across 23 Amazon marketplaces, is free, needs no account, and is made by Ordinary Systems LLC.

Editorial use is fine, no permission needed. Please don’t alter the logo or use it in a way that suggests we endorse a product.
Getting it right
Four things that get muddled in coverage. The distinctions matter to us, and the first one is the whole story.
Pseudo-brands, not counterfeits
The names Knockoff flags are real trademarks, legally registered, sitting on commodity goods. That is a different problem from counterfeiting, and a more interesting one. Knockoff makes no claim about whether any product is a counterfeit.
Not a review checker
Knockoff does not read reviews or judge whether they are fake. That was Fakespot’s job and it is a different category of tool. Knockoff judges the brand behind a listing, in search results, before anyone clicks.
The verdicts are heuristics, not ground truth
Unknown names are scored, and scoring is fallible. Filtering a real brand is treated as the worse failure, so the tuning is deliberately cautious. Every verdict is one click from being overridden, and accepted corrections reach every install within a day.
Country filters, but only when asked
Listings show where a seller is based, and a shopper can choose to hide sellers from specific countries. That list starts empty, lives only in their browser, and when it is set those listings are hidden outright rather than dimmed. What country never does is feed the automatic brand verdict. The appraisal is about disposability, not geography, and plenty of established brands manufacture where the junk does.
