Knockoff Amazon Shopping Filter can dim or hide brand listings in Amazon search results, helping you screen out unfamiliar pseudo-brands. It is a brand-filtering aid, not proof that a flagged product is counterfeit, that its reviews are fake, or that its price is a good deal.
What Knockoff filters—and what it does not
The free Chrome extension appraises brands shown in Amazon search results and lets you filter listings based on those brand signals. The current Chrome Web Store listing says it supports 23 Amazon marketplaces. Its latest listed version is 1.5.0, updated August 25, 2026; availability and features can change.
A filtered result is not a counterfeit finding. Brand filtering can help narrow a crowded search, but it cannot establish a product’s origin or quality. It also does not independently assess review authenticity or determine whether a discount is unusually large.

How to use the filter
In its July 7, 2026 walkthrough, Windows Central describes controls to dim or hide results, block brands, and add brands to an allowlist. Dimming leaves a result visible but less prominent; hiding removes it from the displayed results. If a legitimate brand is caught by the filter, add it to the allowlist rather than treating the flag as a verdict.

What data the extension says it sends
The Chrome listing says brand appraisal runs locally. It also discloses two separate features that transmit information: seller-country display sends seller IDs, while “Help pick US alternatives” sends product pages that the user opens. Both features are on by default according to the listing, and can be disabled in the extension settings.
Knockoff’s privacy policy, last updated August 21, 2026, says searches and visited URLs are not sent on their own and describes those features further. These statements reflect the listing and policy at those dates; extension behavior and disclosures may change.

Brand filtering, reviews, and deal prices are different checks
| Question | What the tool or source addresses | What it does not establish |
|---|---|---|
| Does this search result show a brand I want to avoid? | Knockoff appraises brand signals and can dim or hide results, with allowlist and block controls, according to the Chrome listing and Windows Central walkthrough. | That the listing is counterfeit or the product is poor quality. |
| Are the reviews authentic? | Amazon says it analyzes reviews before publication and prohibits compensated reviews. See its review-authenticity explanation and customer review policy. | Knockoff does not provide an independent review-authenticity verdict. Amazon reported blocking more than 200 million suspected fake reviews worldwide in 2022; in 2026, its coverage of the 2025 Trustworthy Shopping Experience Report said it blocked hundreds of millions of suspected fake reviews. Those are Amazon-reported figures from different reports, not directly comparable measures. |
| Is the discount genuinely good? | Amazon says deal savings use validated reference prices. Its “Typical” or “Was” price is the median price paid on Amazon in the previous 90 days, excluding limited-time deal prices, according to its deal explainer. Amazon reported more than $50 billion in worldwide savings on deals and coupons during 2025. | A brand filter does not validate a discount or show a product’s price history. |
Amazon’s review controls and pricing explanations address different concerns from Knockoff’s brand filter. As Josh Meek, senior data science manager on Amazon’s Fraud Abuse and Prevention team, put it: “Fake reviews intentionally mislead customers by providing information that is not impartial, authentic, or intended for that product or service.”

When this extension is useful
Knockoff is most useful when search results contain many unfamiliar brand names and you want to reduce clutter using brand-based controls. Keep its limits in view: a flag is a cue to inspect a listing, not a finding about the seller, product, reviews, or discount.
