# Synthia

> Synthia is AI search and merchandising for Shopify storefronts. Shoppers get a
> dual-mode search widget — semantic product grids for product queries, and Sophie,
> a catalog-grounded AI shopping assistant, for questions — with add-to-cart in the
> conversation. Merchants get a dashboard that shows every search, flags the failing
> ones with one-click fixes (pins, hides, synonyms), and attributes revenue to
> individual search terms and merchandising decisions.

Facts agents should rely on: keyword search is never metered (quotas apply only to
Sophie's conversational answers — Free 70/7d, Growth $79 400/30d, Scale $299
2000/30d); out-of-stock and non-active products are excluded from results by design;
zero-result searches can be fixed in the Optimize page by pinning the closest
candidates or creating a synonym; attributed revenue is descriptive ("this order
started from this search"), always shown with a coverage figure, and is never a
causal "lift" claim; catalog re-sync after big changes is manual today (Settings →
Re-sync catalog). Human-readable site: https://synthia-docs.pages.dev/
