It is not designed for early-stage direct-to-consumer storefronts or small merchants that require turnkey, out-of-the-box marketplace plug-ins. ## What it is Constructor is an AI-native search and product discovery platform built specifically for enterprise online retail and B2B commerce. Rather than relying solely on traditional keyword indexing or opaque ranking models, the platform runs on a proprietary Commerce Reasoning Engine. This engine synthesizes behavioral signals, shopper context, and catalog data to interpret query intent and dynamically order items across every touchpoint. The suite encompasses onsite discovery channels such as semantic search, predictive autosuggest, faceted category browse, dynamic collections, and personalized recommendation carousels. In addition to core search, Constructor provides interactive discovery through conversational shopping agents, a Product Insights Agent that answers complex product queries, and interactive recommendation quizzes. Merchandisers can also deploy retail media capabilities, serving targeted sponsored listings alongside organic catalog results without degrading search relevance. For operational management, Constructor provides glass-box merchandiser controls alongside GenAI-driven attribute enrichment and a Merchant Intelligence Agent, giving merchandisers visibility into ranking decisions and enabling intervention when manual boosts or experiments are necessary. Operating as an API-first, headless, and platform-agnostic service, Constructor integrates into existing e-commerce stacks and supports offsite personalization across email, SMS, mobile alerts, and in-store environments. **What makes it different:** Constructor distinguishes itself by combining real-time behavioral reinforcement learning with a transparent 'glass-box' reasoning engine, allowing merchandisers to inspect ranking logic, audit algorithmic decisions, and apply specific controls instead of relying on an untraceable black box. **Best for:** enterprise retailers and high-volume B2B brands wanting AI-driven site search, personalized browse, and transparent merchandising controls **Not ideal for:** small storefronts with minimal catalogs or teams seeking self-serve, off-the-shelf basic search plugins ## Key features - **Commerce Reasoning Engine** — Processes behavioral signals, context, and intent in real time to deliver optimized product discovery results across all shopper channels. - **Search & Autosuggest** — Delivers personalized, typo-tolerant search queries and instant autocomplete recommendations trained on buyer interaction data. - **AI Shopping & Insights Agents** — Conversational agents that understand natural language queries and answer detailed product questions directly on the storefront. - **Dynamic Browse & Personalization** — Automatically organizes and personalizes category landing pages to maximize conversion based on individual shopper preferences. - **Retail Media Network Support** — Monetizes catalog traffic by inserting relevant sponsored products and ad placements without compromising organic user experience. - **Merchant Intelligence & Glass-Box Controls** — Provides intuitive merchandising dashboards, A/B testing, and diagnostic tools to explain and adjust algorithmic ranking factors. - **GenAI Attribute Enrichment** — Automatically enriches product and category attributes using generative AI to expand catalog completeness and discoverability. - **Omnichannel & Offsite Discovery** — Powers personalized product recommendations across external touchpoints including email, SMS, mobile push, and in-store systems. ## Use cases - **Replacing Legacy Site Search** — Upgrades slow or irrelevant keyword-matching search engines with natural language understanding and machine-learned relevance. - **Automated Category Merchandising** — Dynamically re-ranks product listing pages (PLPs) based on live behavioral data and margin goals, reducing manual merchandising hours. - **Interactive Shopping Assistance** — Guides shoppers through complex product evaluations using interactive quizzes and conversational AI shopping assistants. - **Monetizing Onsite Search with Sponsored Ads** — Enables retail brands to run retail media networks with targeted sponsored product slots integrated cleanly into organic results. ## Pros - Transparent 'glass-box' AI enables merchandising teams to inspect and understand ranking decisions - API-first, composable architecture integrates flexibly across headless e-commerce frameworks - Enterprise-grade security verified by independent SOC2 Type 2 and ISO27001 assessments - Comprehensive coverage across search, browse, recommendations, interactive agents, and retail media ## Limitations - Requires custom enterprise scoping with no public self-service pricing tiers - Implementation requires engineering and integration overhead compared to simple store plug-ins ## Pricing At the review date, Constructor does not publish flat-rate subscription tiers.
