Knockoff, a free open-source browser extension, lets Amazon shoppers dim, label or fully hide pseudo-brand listings and sponsored ad carousels cluttering search results.
5,000 established brands anchor its filtering, while linguistic heuristics flag all-caps or unpronounceable names; users can choose Relaxed, Standard or Strict modes.
On-device processing is central to the tool’s pitch: it requires no accounts, cookies or analytics scripts, with network traffic limited to daily brand-list updates.
Josh Pigford built the extension to counter Amazon’s flood of white-label, trademark-squatting sellers that has made finding established products increasingly difficult.
