Knockoff Amazon Brand Filter

Last updated: 12 October 2026

What Knockoff does

Search Amazon for something ordinary, like a dog bed, and much of the first page comes from sellers with names nobody can pronounce. They are real registered trademarks, but they belong to sellers with almost no history and nothing to lose if the product is poor.

Knockoff runs the moment your results load. It checks the brand on every listing and decides whether it looks like an established company or a throwaway name. Then it acts on that verdict in the way you have chosen.

The developer, Josh Pigford, built it after struggling to find a well-made grass trimmer on Amazon. He told Fast Company that "everything I was finding were those nonsensical brandnames with almost no selling history." Knockoff launched in July 2026.

How the Knockoff Amazon brand filter decides

1. The known-brands list: Knockoff keeps a register of more than 6,000 established brands, refreshed daily. A name on it passes untouched.
2. The name score: Knockoff scores an unknown name on how much it looks like keyboard mashing, such as random capitals, missing vowels and consonant runs no word would have.
3. The community list: one-click reports from users feed a shared list, and accepted fixes reach every install within a day.

Established Chinese companies such as Anker and DJI are on the known-brands list, so Knockoff treats them like any other real brand. Knockoff draws its line at whether a company has a reputation to lose, not at where it is based.

Knockoff's settings

• Filter level: Relaxed catches the worst offenders, Standard adds suspect and unbranded names, and Strict lets through only recognised brands.
• What happens to flagged items: hide them, dim them until you hover, or just add a warning label.
• Your own lists: mark any brand as trusted or junk from the results page, and your choice overrides every other signal.
• Sponsored listings: a separate switch strips Amazon's paid "Sponsored" results. It is off until you turn it on.
• Alexa promos: another switch hides Alexa banners and the assistant panel that opens on its own.
• Seller country: Knockoff shows where a seller is based on more listings, using the VAT number on European listings where Amazon publishes no address.
• Past orders: since version 0.10 it labels made-up brands in Your Orders, so you can see which past buys came from one.

Where it works

Knockoff runs on 23 Amazon stores, including amazon.co.uk. You can install it in Chrome from the Chrome Web Store, and Edge, Brave and Vivaldi use that same listing. There is a Firefox add-on for desktop and Android.

On a Mac, iPhone or iPad, it comes as a Safari extension from the App Store. It needs macOS 11 or iOS 15 and later, and you switch it on in Safari's settings after installing.

Privacy

Knockoff asks for one browser permission, storage, so it can remember your settings. It only runs on the shopping sites it supports, and your searches and orders stay in your browser.

Two features do send data, and both are on until you switch them off. Seller country sends seller IDs. "Help pick US alternatives" sends the product you open, meaning its title, brand and Amazon product number, but nothing that identifies you. The filtering still works with both switched off. The Knockoff FAQ lists every call it makes.

What the Knockoff Amazon brand filter will not do

Knockoff judges the brand behind a listing. It never reads reviews, so it cannot tell you whether a listing's five-star reviews are genuine. It also cannot spot a counterfeit, where a seller fakes a real brand's name. The tool deals with the opposite problem: a real trademark on generic goods.

Its verdicts are a best guess from lists and a name score, so expect the odd mistake. It could flag a small British maker with an unusual name. If that happens, mark the brand as trusted and it stays that way.

It does not track prices either. For price history and price-drop alerts on Amazon, you need a separate price tracker.

Fake reviews and pricing in the UK

UK consumer law bans fake reviews and misleading price claims. The Competition and Markets Authority sets out what counts in its unfair commercial practices guidance. Knockoff does not check either of those. What it does is cut down the number of throwaway sellers you have to judge in the first place.

How to get it

Install the Knockoff Amazon brand filter from your browser's add-on store, then search Amazon as normal. Flagged listings change at once, and a counter on the page tells you how many it filtered.
