Overview
How each tool is described
Lily AI
What is Lily AI?
Lily AI is the company behind Lily Max, an agentic product intelligence platform that enriches retail catalogs with structured, machine-readable product data for advertising, onsite discovery, organic and AI search, and agentic shopping experiences.
- Product intelligence: Lily Max generates and maintains product attributes, descriptions, metadata, schema, classifications, conversational attributes, and other product signals so search engines, ad platforms, onsite systems, answer engines, and shopping agents can better understand each item and match it with shopper intent.
- Continuous testing workflow: goal-based agents detect gaps in existing product data, generate enrichment in consumer language, launch controlled experiments, measure performance against holdout groups, and scale winning changes across the broader catalog. Lily documents methodologies including matched-spend A/B testing and difference-in-differences analysis rather than treating generated enrichment as automatically beneficial.
- Channel activation: Lily Max currently supports four main surfaces: Google Ads, Meta Ads, onsite search and merchandising, and AI discovery/agentic commerce. Its AI-discovery work includes feed enrichment, metadata, schema, crawlable PDP content, and conversational attributes designed to improve product readability for systems such as Google AI experiences, ChatGPT, Gemini, Claude, and Perplexity, without guaranteeing placement or citation.
- Commercial considerations: Lily does not publish a fixed rate card. Pricing is tailored according to factors including catalog size, selected use cases or channels, markets and regions, and advertising spend. Lily also currently offers a free 30-day trial on 500 products for teams starting with Google Merchant Center data.
Lily AI is most relevant to retailers and brands that want to improve how their catalogs are interpreted, tested, and surfaced across paid media, onsite discovery, conventional search, and emerging AI-mediated shopping environments.
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.
