Constructor

Ecommerce search and product-discovery platform whose ranking is trained on clickstream data, with personalization as one layer.

Visit Constructor Alternatives

Constructor is primarily a site search and product-discovery platform for ecommerce, built around ranking models trained directly on a retailer's clickstream and conversion data rather than a keyword index adapted for shopping. Personalization is one feature of that broader system: result ranking, recommendations and collections adapt to a shopper's individual behavior and inferred intent, alongside AI shopping agents and product-insight tools layered on the same data. It should be understood honestly as a search-and-merchandising product whose personalization is a byproduct of the ranking engine rather than a dedicated personalization or recommendation platform bought on its own. It is a cloud API/SaaS product aimed at mid-market and enterprise retailers optimizing for revenue and conversion metrics, and competes most directly with other AI-driven ecommerce search vendors rather than general-purpose recommendation engines.
