Knockoff.

Knockoff

Knockoff is a privacy-first browser extension that transforms your Amazon shopping experience by filtering out trademark-squatting pseudo-brands and counterfeit sellers. With over 75,000 daily users, it helps you discover authentic products from reputable companies while keeping your browsing data completely private and local.

Product Highlights

• Smart Brand Detection: Automatically identifies and filters pseudo-brands using linguistic pattern analysis, checking against a curated database of 5,000+ established brands refreshed daily.
• Three Filter Levels: Choose from Relaxed, Standard, or Strict filtering modes to control exactly how aggressively Knockoff hides, dims, or labels suspicious listings.
• Complete Privacy: No accounts required, no tracking, and no analytics—your shopping data never leaves your browser with all processing done locally.
• Customizable Controls: Hide sponsored ads, create personal trust/block lists, and override any filter verdict with a single click.
• Community-Driven Accuracy: Report misclassifications to improve the brand database, with updates reaching all users within 24 hours without requiring extension updates.

Use Cases

• Quality-Conscious Shoppers: Eliminate frustration from sifting through obscure pseudo-brands like SZHLUX or HORUSDY to find products from companies with actual reputations and customer service.
• Privacy-Focused Consumers: Shop Amazon confidently knowing no browsing history, purchase patterns, or personal data is collected, stored, or transmitted to third parties.
• Efficient Product Research: Save time by automatically dimming or hiding low-quality listings and sponsored ads that clutter search results, surfacing genuine brands faster.

Target Audience

Knockoff is designed for online shoppers who value product quality and brand authenticity over the lowest price, particularly those frustrated by Amazon's proliferation of mysterious private-label sellers. It appeals equally to privacy advocates seeking transparent, ethical software and busy consumers who want cleaner, more trustworthy search results without sacrificing convenience.
