Most Magento AI chatbot demos look impressive until a shopper asks about a size that is out of stock, a configurable option that changed last week, or a SKU that marketing renamed. Without a reliable catalog sync into the assistant’s retrieval layer, answers drift — and trust evaporates.
Tenant isolation is non-negotiable
Multi-store Magento estates cannot share a single knowledge blob. Every query must resolve to a verified store_id from the session token, not from a browser-supplied store code. That is how you keep Product A on Store B from leaking into another merchant’s chat.
What “catalog-aware” means in practice
At minimum: periodic or event-driven product sync, attribute facets the model can cite, stock signals that gate add-to-cart suggestions, and a clear fallback when retrieval confidence is low. Hyvä themes add a second requirement — a lean Alpine widget that does not fight the storefront’s CSS or Core Web Vitals budget.
High-touch beats self-serve for Magento
Magento integrations are rarely one-click. Manual module install, OAuth or integration tokens, CORS allow-lists, and knowledge curation take days — not minutes. Price the setup honestly (€1,200 net one-time is realistic for a single store) and reserve self-serve billing for later.
