Where's That From? com. The tool addresses concerns about the prevalence of low-quality imitation goods in the online marketplace by making it easier to determine where a product is coming from before making a purchase. It does this by analyzing seller information, brand names, and trademark data, and then displaying its findings above the Buy box on Amazon product pages.

The extension employs several detection heuristics, including trademark lookups, company name analysis, brand name analysis, and seller address verification. These methods are used to make an informed guess about a product's origin, though the tool notes that its analysis is a best-effort and cannot guarantee complete accuracy. For enhanced detection, users can configure the extension to enable trademark searches, which involves sending the product name to the Where's That From server to query US Patent and Trademark Office data. By default, all processing is done locally in the browser, and information is not retained beyond what is necessary for the lookup. The tool emphasizes that user data is never stored, sold, or shared with other entities.

Where's That From? is available as an extension for both Firefox and Chrome browsers, with the Chrome version also being compatible with Microsoft Edge, although it is not listed in the Edge extension store. The extension is intended for use exclusively on the US version of Amazon and does not support other country-specific Amazon sites. The service is aimed at online shoppers who want greater transparency about the products they are considering, particularly regarding the country of origin and potential ownership changes of brands.
