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.
Klevu
What is Klevu?
Klevu is an AI-powered ecommerce search and product-discovery technology that became part of Athos Commerce after combining with Searchspring in 2025. Klevu remains supported for existing customers, while Athos Commerce is now the broader commercial platform and migration path for search, merchandising, personalization, recommendations, and product discovery.
- Search experience: Klevu uses machine learning, natural-language processing, autocomplete, behavioral data, and catalog information to understand shopper queries and rank relevant products. The newer Athos AI Search extends this approach with hybrid semantic and keyword search plus behavioral signals that continuously refine results.
- Merchandising and personalization: Klevu supports manual product pinning, boosting rules, category merchandising, and scheduled campaigns while machine learning continues to influence the remaining rankings. Current Athos capabilities expand this with rules based on inventory, trends, segments, shopper history, and real-time intent, alongside AI-assisted merchandising recommendations.
- Commerce integrations: Klevu has prebuilt integrations for Shopify and Shopify Plus, Adobe Commerce/Magento, BigCommerce, commercetools, Salesforce Commerce Cloud, and Shopware. SDKs and APIs support headless and custom storefront implementations, while Klevu’s existing Discovery Suite can power search results, category pages, and product recommendations.
- Commercial considerations: new Athos Commerce customers receive quote-based pricing. Its Onsite Discovery plan includes Search, Merchandising, and Personalization, with AI Search, AI Merchandising, AI Product Recommendations, and AI Product Bundling available as add-ons. Single products and custom combinations can also be quoted, so buyers should distinguish current Athos packaging from legacy Klevu subscriptions.
Klevu is most relevant to ecommerce teams that want established AI search and merchandising technology without building product-discovery infrastructure internally, while buyers evaluating it today should also consider the ongoing transition to the unified Athos Commerce platform.
