Amazon is flooded with trademark-squat "brands": random strings like SZHLUX, HORUSDY, and LATTOOK, registered at the USPTO purely to unlock Amazon Brand Registry. They sell commodity goods with no company, no warranty, and no reputation behind them. Knockoff is a Safari extension that appraises every listing's brand right in your Amazon search results and hides, dims, or labels the junk, so what's left is brands with a reputation to lose. Works on iPhone, iPad, and Mac. Featured in Fast Company, Gizmodo, 404 Media, PC Gamer, Yahoo, and Lifehacker. HOW IT WORKS • Every brand is checked against a curated register of established brands, refreshed daily. • Unknown names are scored on the linguistic signature of pseudo-brands: all-caps squat-length strings, vanishing vowels, unpronounceable consonant runs. • Your allowlist and blocklist override everything. FEATURES • Hide, dim, or label flagged listings, with a one-click reveal. • Optionally hide Amazon's paid "Sponsored" listings too (off by default). • Three filter levels: Relaxed, Standard, Strict. • Trust or block any brand in one click, right from the results. • One-click misclassification reporting that improves the shared lists for everyone. PRIVATE BY DESIGN Knockoff works only on Amazon pages. It has no access to your browsing history and never sees the other sites you visit. The brand appraisal runs locally on your device. No accounts, no profiles, nothing tied to you. Two features send data. Both are on by default, and both can be switched off in settings: seller country sends seller IDs, so it can show where a seller is based; and Help pick US alternatives sends the product pages you open, so we know which products people want US alternatives for. A stored row records that a product was viewed N times, never who viewed it. Never sent: your searches, your orders, or anything you type into a page. Reports stay opt-in and anonymous. Full detail: knockoff.co/privacy Free. Works on 23 Amazon marketplaces worldwide, including amazon.com, .ca, .co.uk, .de, .fr, .co.jp, .in, and .com.au. To turn it on: enable Knockoff in Safari's Extensions settings and allow it on Amazon. Search as usual, and the junk brands drop out. ## Key features - Hides, dims, or labels flagged listings - Filters sponsored listings - Three filter levels: Relaxed, Standard, Strict - Allowlist and blocklist functionality - One-click misclassification reporting - Works on iPhone, iPad, and Mac ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/knockoff-shopping-filter/id6788401939/reviews.md ### 5/5 — Definitely a KEEPER *2026-07-22* Easily installed on Safari. Enabled it for US Amazon. I didn’t use the “hide” option because I wanted to see what would happen. I am totally impressed. I love the labels identifying source location or lack thereof. I also love the “No Brand” label. All brilliant! If this extension does nothing else, I’m celebrating. ### 5/5 — Super Helpful *2026-07-20* This developer has put in the work to make web shopping somewhat bearable again. It works great and he responds to all feedback. ## Frequently asked questions about Knockoff ### What is Knockoff? Knockoff is a Safari extension designed to help you identify and filter out suspicious or fake brands on Amazon. It works by appraising brands directly in your search results, hiding or labeling those that lack reputation. ### How does Knockoff work? It checks every brand against a curated list of established brands and scores unknown names based on linguistic patterns common in fake brands. You can then choose to hide, dim, or label these flagged listings. ### Is Knockoff free to use? Yes, Knockoff is completely free to use. It does not have any in-app purchases or advertisements, offering a clean filtering experience. ### What devices does Knockoff support? Knockoff is available for iPhone, iPad, and Mac devices. It functions as a Safari extension, integrating directly into your browsing experience on these platforms. ### Does Knockoff collect my browsing data? Knockoff is designed with privacy in mind. It only operates on Amazon pages and does not access your general browsing history. Brand appraisal runs locally on your device, and data collection is opt-in and anonymous. ### How often is the brand list updated? The curated register of established brands used by Knockoff is refreshed daily. This ensures that the app's filtering capabilities are consistently up-to-date with the latest brand information. ### Can I customize the filtering levels in Knockoff? Yes, Knockoff offers three filter levels: Relaxed, Standard, and Strict. You can also create your own allowlist and blocklist to further personalize which brands are displayed or hidden. ### What is the rating for Knockoff? Knockoff has a rating of 1.0 stars from 1 rating. This indicates a very limited user feedback base at this time. ## Version history (last 5 releases) ### 1.4.0 — 2026-08-18 - New: the number of items Knockoff filtered now shows on the toolbar icon, the way an ad blocker does. The count is per tab, so it follows whatever you're looking at. - New: two switches in Options > Display turn off the on-page interface. "Show the corner Knockoff button" hides the bottom-right button, and "Show the filtered count on the page" hides the corner pill. Both stay on by default. With both off, Knockoff still filters, the count still shows on the toolbar icon, and hidden items are still recoverable from the panel. ### 1.3.1 — 2026-08-11 - Fixed: country flags rendered as boxed letters ("CN CN") on Windows. The bundled flag font never loaded on Amazon pages, and macOS hid the problem behind its own flag glyphs. - Fixed: on an Etsy listing page, the panel could report a different shop's age, saying "on Etsy about 17 years" for a shop that opened two months ago. The shop is now read from the listing's own data instead of the first image on the page, which was sometimes a recommendation from another shop. - Fixed: trusting a brand now spares its product lines too. Trust "Jo Coffee" and a title like "SOME FUN JO: 24 Cups..." is no longer read as the pseudo-brand "SOME". Blocking still needs the exact name. - Fixed: with "Hide Alexa promos" on, the "Ask Alexa" tooltip that Amazon pops over selected text is hidden too. ### 1.0.1 — 2026-07-29 - Fixed: on Safari, turning on Etsy checking now works. The switch in settings did nothing, because Safari only asks for site access while you're on the site itself, from its own toolbar button. Knockoff now points you to Etsy and lets Safari ask there. Needs Safari 17 or later. ### 0.12.0 — 2026-07-24 - New: hide sellers by country. Pick countries in the in-page panel and Knockoff hides listings from sellers based there, right where the seller flags show. Only sellers Knockoff can identify are ever hidden. Unknown sellers are left alone, and you can undo it from the hidden listing or the panel. - New: pseudo-brands are now filtered inside Amazon's "Sponsored" brand carousels (the product-collection strips), not just regular search tiles. - Improved: the badge on low-rated listings now says what it caught ("Low rating", "No ratings", or "Few reviews") instead of showing the brand name, which read as a call against the brand itself. - Improved: fewer good brands mistaken for junk. Listings that lead with generic words like "Accessories" or "Compatible" are no longer read as brand names. - Improved: seller flags now resolve for more sellers outside the US. - Improved: the "Find US alternatives" button now stays on flagged-junk brands even when they're sold by a US seller. - Fixed: shoes and other fashion listings on Amazon's mobile site no longer show "No brand". The brand is now read from mobile-web cards. ### 0.9.0 — 2026-07-19 - New: a "Send feedback" form built into the control panel. Tell us about a brand we missed, a bug, or an idea in a couple of clicks. Leave an email if you'd like a reply, or don't. It sends your note and the address of the page you're on, and nothing else. - New: on iPhone and iPad, where Safari buries the toolbar button behind the "aA" menu, Knockoff now shows a small button in the bottom corner that opens its panel. The panel opens as a bottom sheet you can swipe away, with the filtered count and the show-hidden toggle inside it. The count pill that used to flicker while counting is fixed on desktop too. - Improved: the "Likely junk seller" warning on a product page is now a button. Click it to Trust, Block, or report the seller as legitimate, the same one-click controls you already have on brands. - Improved: Knockoff now sits out Amazon's grocery storefronts the way it already skips books and media, so everyday food staples aren't mistaken for pseudo-brands. - Improved: fewer false flags. Connector words at the start of a listing title, real brands on Amazon's eco-tagged recommendation tiles, and short all-caps seller initials are no longer mistaken for pseudo-brands. - Improved: the "Find US alternatives" button now appears only on amazon.com and only when "Help pick US alternatives" is on. It no longer showed up on other marketplaces or when the setting was off. - Windows: seller-origin flag chips now show real flags instead of the country code twice, like "US US". Windows has no flag emoji, so Knockoff now bundles a small flag font. ## More apps by Ordinary Systems, LLC - [KeptWell Care](https://appshunter.io/ios/app/keptwell-care/id6762662005) All apps by Ordinary Systems, LLC: https://appshunter.io/developer/365902614 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
