Unlike many recommendation engines, Rex is developed and hosted entirely within the EU. That means full GDPR compliance, strong data protections, and no legal gray areas.
Most systems rely on static rules or product similarities. Rex goes further—tracking deep behavioral signals like scrolls, pauses, and revisit patterns to deliver smarter, intent-aware recommendations.
Advanced, behavior-based recommendation systems are rare—and even fewer are built to meet the needs of European ecommerce. Rex is proudly one of the only platforms in this space.
From onboarding to insights, everything about Rex is built for ease. You don’t need a team of engineers or clean data to get started.
No black boxes here. Rex shows why each product was recommended, in plain language, so your team and your customers always understand the why.
Our AI dynamically adapts recommendations as visitors browse, capturing immediate insights without any disruption or delay, for an uninterrupted shopping experience.
Instantly craft unique product recommendations that align precisely with each shopper’s behavior, interests, and intent—driving higher engagement and increased sales.
