About tatGuard — Online Fake & Scam Protection
tat (noun, British slang): cheap, low-quality, or counterfeit goods.
tatGuard analyses product listings and helps you make an informed decision before buying.
How it works -
Open any product page on an e-commerce or secondhand marketplace and click the tatGuard icon. In seconds you get a risk score from 1–10, a plain-English verdict, and a breakdown of exactly what raised concerns. tatGuard works on budget marketplaces, auction sites, secondhand platforms, and independent retailers alike.
What tatGuard checks -
Counterfeit risk — is this product imitating a known brand?
Safety risk — are there specific concerns about materials or compliance?
Quality risk — do reviews and external sources suggest poor build quality?
Seller trust — feedback score, history, and red flags
Price anomaly — is the price implausibly low for what’s being sold?
Image analysis — AI vision scans the product photo for brand copying
Free to use -
10 free scans on install — no account needed. After that, keep scanning free for 7 days with an email signup.
Premium from £4.99/month for 50 scans per day.
Privacy -
tatGuard only reads pages you actively scan. It does not track your browsing, build profiles, or sell your data. Full privacy policy at cosmolabs.co.uk.
