亚马逊透镜 is a free Chrome add-on developed by 极爱智能. This add-on allows users to quickly analyze product information on Amazon's listing pages without having to click into individual product pages. With 亚马逊透镜, users can easily determine the brand registration status, number of sellers, price range, number of FBA sellers, and number of mainland China and Hong Kong sellers for each ASIN listed on the page.

The add-on utilizes a web crawler to match brand registrations from a trademark database, which includes data from WIPO, EUIPO, and the USPTO. However, it's important to note that the add-on's brand registration check is not 100% accurate due to the dynamic nature of trademark data. Users have the option to manually update the registration number for any missed brands.

Please be aware that recent updates to Amazon's listing pages have made it necessary for 亚马逊透镜 to fetch data from product detail pages instead of the listing pages. Additionally, the add-on is no longer able to display seller information such as the number of sellers, price range, FBA sellers, and mainland China and Hong Kong sellers on the offer-listing page.
