Josh Pigford’s Knockoff Extension Draws 10,000s of Downloads as It Filters Fake Amazon Brands

Summary
Tens of thousands of users downloaded Knockoff within days of its Tuesday launch, turning Josh Pigford’s Amazon-filtering browser extension into a viral shopping tool.
The free, open-source add-on for Chrome, Firefox and other Chromium browsers grays out or hides suspected fake brands locally on-device, without accounts or data sent to company servers.
Hands-on testing found it worked best in categories flooded with no-name listings—such as solar lights—while leaving established vacuum brands mostly untouched.
Accuracy still needs tuning: Knockoff wrongly flagged legitimate brands including Torras and left some real brands marked as unrecognized, though users can submit manual correction reports.
The tool builds on earlier Amazon brand filters and reflects broader frustration with a marketplace crowded by white-label products, suspicious reviews and weak seller support.
