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.
Also on Safari and Firefox. Free, no accounts. Works on every Amazon marketplace.
Junk gets flagged, dimmed, or hidden. Your call. Real brands pass untouched.
Over 100,000 people shop with Knockoff.
As featured in
Every listing, appraised in place.
It happens the moment your results load, on every Amazon page you open. Nothing to click, nothing to wait for.
Checked against 5,000+ real brands
A curated register of established brands, refreshed daily. Real brands pass instantly.
Unknown names get scored
Junk brands read like keyboard mashing: random capital letters, no real word in there. Knockoff scores every unknown name on how much it looks like that.
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.
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.
Hide sponsored ads
Flip one toggle to strip Amazon’s paid “Sponsored” listings out of search, too. Off by default. Your call.
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.
