Overview

AI-assisted counterfeit and scam detection for secondhand marketplace listings.

MarketplaceGuardian is an AI-driven counterfeit detection tool for the independent usage of online shoppers on secondary marketplaces. Apart from detecting counterfeits, MarketplaceGuardian provides helpful resources from U.S. federal and state sources to help customers avoid financial fraud. We focus on offering logic and detailed reports behind each result and flag so users can learn why a listing was flagged rather than just receive a flat answer. Perfect accuracy is not guaranteed, and the app should instead be treated as an assistive signal.
