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 curated register of established brands, 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.
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.
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
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.
