Overview
How each tool is described
Nosto
What is Nosto?
Nosto is a Commerce Experience Platform that helps ecommerce brands personalize online shopping experiences using shopper behavior, product data, and AI-driven optimization. It combines product recommendations, personalized search, category merchandising, content personalization, and experimentation tools to help retailers improve product discovery and create more relevant customer journeys across digital storefronts.
- Commerce personalization: Nosto analyzes shopper behavior, product catalogs, and customer segments to personalize experiences such as product recommendations, search results, category pages, and onsite content.
- Product discovery and merchandising: retailers can manage how products are presented through personalized merchandising campaigns, search optimization, category management, and audience-based shopping experiences.
- AI and optimization: Nosto uses its experience.AI™ technology to support personalization decisions by analyzing commerce data and shopper interactions to improve relevance across the customer journey.
- Ecommerce workflow integration: Nosto is designed to work with ecommerce platforms and marketing technologies, allowing brands to connect personalization capabilities with their existing digital commerce stack.
Nosto is most suitable for ecommerce teams that need deeper control over product discovery, personalization, and merchandising across online stores rather than relying only on standard storefront experiences.
Constructor.io
What is Constructor.io?
Constructor, commonly associated with the Constructor.io name, is an AI-native product discovery platform for enterprise ecommerce. Its current Commerce Reasoning Engine uses behavioral clickstream, catalog, contextual, and other commerce data to power connected experiences across Search, Browse, Recommendations, Collections, and AI shopping agents.
- Search and ranking: Constructor Search combines clickstream signals with transformers, LLMs, and other machine-learning techniques to interpret queries and personalize rankings in real time. Ranking can be optimized against ecommerce objectives such as revenue per visitor, conversions, average order value, profit, or another retailer-defined KPI while incorporating shopper history and context.
- Discovery workflow: Browse, Recommendations, and Collections reuse behavioral learning across the discovery experience rather than operating as isolated engines. Recommendations use the same personalization signals as Search, while Browse feeds subsequent customer behavior back into other Constructor products. AI Shopping Agent adds conversational discovery using natural-language intent, product data, clickstream behavior, and the wider Constructor discovery stack.
- Merchant control: merchandisers can configure facets and create boosting, burying, slotting, blocklisting, and other searchandising rules across Search, Browse, Collections, Recommendations, and related experiences. Merchant Intelligence Agent (MIA) explains rankings and performance in natural language, suggests actions, and can draft merchandising changes for review and approval.
- Commercial considerations: Constructor uses a demo-led enterprise sales process rather than publishing fixed self-service subscription prices. Buyers should evaluate catalog scale, clickstream availability, ecommerce integrations, rollout requirements, KPI configuration, merchandising governance, and which discovery modules they need.
Constructor is particularly relevant to enterprise retailers that want search, category browsing, recommendations, merchandising, and conversational discovery to learn from the same shopper signals instead of running as separate personalization systems.
