Amazon, without the knockoffs.

Knockoff filters the trademark-squat pseudo-brands (the SZHLUXes and HORUSDYs) out of your search results, so what's left is brands with a reputation to lose.

Free, fair source (FSL), no accounts, no tracking. Works on amazon.com, .ca, .co.uk & .com.au.

Junk gets flagged, dimmed, or hidden. Your call. Real brands pass untouched.

How it works

Every listing, appraised in place.

No accounts, no cloud lookups on your shopping path. The whole appraisal runs locally in your browser, on every Amazon page you open.

1

Checked against 5,000+ real brands

A bundled register of established brands, including the community-maintained AmazonBrandFilterList, refreshed daily. Real brands pass instantly.

2

Unknown names get scored

Pseudo-brands have a linguistic signature: ALL-CAPS squat-length strings, vanishing vowels, unpronounceable consonant runs. Knockoff scores every unknown name against it.

3

You set the strictness

Relaxed, Standard, or Strict, and flagged items are hidden, dimmed, or just labeled. Every verdict is one click from being overridden.

Features

Built like a tool, not a toy.

Hide, dim, or label

Filtered listings can vanish entirely (with a one-click reveal), fade until hovered, or just wear a warning chip.

Your lists win

Trust or block any brand from the results page. Your personal lists override every other signal, always.

Three filter levels

Relaxed catches the notorious offenders. Standard adds suspect names and unbranded listings. Strict allows only recognized brands.

Community reporting

One-click misclassification reports feed a curated list that reaches every install within a day, no update required.

Private by design

No accounts, no analytics, no tracking. The only network request is a daily brand-list refresh. Reports are opt-in and anonymous.

Fair source

FSL-1.1-MIT, converting to MIT after two years. No build step, readable in an afternoon. The brand lists are plain text files, so fixing a misclassification is a one-line PR.

Fair source

Help draw the line.

The junk-brand arms race is only winnable together. Add brands, tune the heuristics, or just report misclassifications from inside the extension. Every fix ships to everyone.
