Knockoff

Browser extension that flags trademark-squat pseudo-brands on Amazon search results.

Browser extensionfreeglobal

Knockoff is a browser extension that detects Amazon product listings sold under throwaway, trademark-squat brand names and hides, dims, or labels them directly in the search results. It checks each listing against known-brand lists and a name-pattern heuristic so legitimate but unusual brand names aren't mistakenly flagged. It is meant for Amazon shoppers who want to buy from real, established brands rather than anonymous private-label sellers.
