knockoff

Knockoff strips the fake brands out of Amazon. Those all-caps pseudo-companies like SZHLUX that exist only as trademark filings get filtered from your search results, leaving products from brands with an actual reputation to protect. It's a free browser extension for Chrome and Firefox built by Josh Pigford, the founder of Baremetrics.

There's nothing to run. Under the hood it layers a list of roughly 5,000 verified brands with linguistic analysis: consonant density, all-caps patterns, the unpronounceable letter salad typical of trademark squatting. Your own allowlist and blocklist override everything, and a sensitivity setting controls how aggressive the filtering gets.

Install it if you buy tools, electronics, or anything where warranty and support matter. Skip it if you shop on price alone; sometimes the no-name cable is fine at half the cost.

The catch: heuristics miss. Mixed-case gibberish can slip through, non-English Amazon stores get English-tuned rules, and some page layouts aren't scanned at all. Treat it as a strong first filter, not a verdict.
