Klevu is built for ecommerce teams whose large catalogs have outgrown their platform’s default search. They choose it for relevant onsite results, practical merchandising controls, and discovery tools that work across established commerce stacks.
Nosto personalizes ecommerce storefronts, giving merchandising teams practical control over recommendations, search, category ordering, and segmented content.
When shoppers cannot put a product into words, Syte uses visual AI to connect images and intent with relevant items across a retailer’s catalog.
Shoppers often know what an item looks like but not the words to search for. ViSenze gives retailers visual search, catalog tagging, and recommendation APIs suited to image-heavy product catalogs.
