Knockoff

Overview

Knockoff is a browser extension designed to remove low-quality, pseudo-brands and keyboard-mashing third-party listings from Amazon search results. It evaluates products against a curated registry of real brands and scores unknown names to highlight legitimate options. Users can customize filter strictness to hide, dim, or label junk items seamlessly across every global Amazon marketplace.

What it does

• - Cross-references Amazon product listings against a curated daily-refreshed register of over 5,000 real and established brands
• - Scores unknown or suspicious seller names based on keyboard-mashing patterns and trademark-squatting heuristics
• - Automatically dims, hides, or labels flagged junk items directly on the Amazon search page as results load
• - Provides customizable strictness levels (Relaxed, Standard, Strict) with simple one-click override options.

Who it's for

• Online Shoppers
• Amazon Consumers
• Deal Hunters
• E-Commerce Buyers

Why it works

• Runs automatically in the background the moment search results load without requiring extra clicks or wait times
• Eliminates overwhelming clutter from trademark-squatting pseudo-brands to surface trustworthy manufacturers with reputations to protect
• Operates entirely for free with zero account sign-up friction across Chrome, Firefox, and Safari
• Supports every international Amazon marketplace without disrupting native shopping workflows.

Founder story

Knockoff was built to solve the frustration of digging through endless pages of unverified, random-letter Amazon seller names to find authentic products. By analyzing naming patterns and maintaining a trusted brand register, the developer created a lightweight browser extension to restore clarity and trust to online retail search.
