Products[edit]

Superfish's first product, WindowShopper, was developed as a browser add-on for desktop and mobile devices, directing users who hover over browser images to shopping Web sites to purchase similar products. As of 2014, WindowShopper had approximately 100 million monthly users, and according to Xconomy, "a high conversion to sale rate for soft goods". Superfish's business model is based on receiving affiliate fees on each sale.^[15]


The core technology, Superfish VisualDiscovery, is installed as a man-in-the-middle proxy on some Lenovo laptops. It injects advertising into results from Internet search engines; it also intercepts encrypted (SSL/TLS) connections.^[7][29]


In 2014, Superfish released new apps based on its image search technology.
