What to include
- Your platform, roughly how large the catalog is, and the queries your current search misses.

Most questions are answered below. The last row searches our docs, so you may not need the email at all.
Both, and the customer never picks. Exact queries like SKUs and product names hit a regional keyword index and return in milliseconds. Vague or conversational queries fall through to semantic search over embeddings. One bar, routed per query.
Shopify through an embedded app that installs the widget and keeps the catalog in sync. Headless and custom storefronts through the public API and the typed SDK, @ribban/cerno, which returns the same results the widget does.
No. Matching is on meaning, not title strings, so sneaker, trainer and kicks find the same shoes and misspellings resolve on their own. You can still add a synonym rule when you want a specific mapping.
Yes. Boost products, hide products, pin a result for a query. Rules apply on top of the model's ranking, never underneath it, and take effect immediately. A copilot in the dashboard turns a plain-language instruction into rules you can review.
On Shopify, usually the same day. Install the app, the catalog syncs, the widget attaches to your theme's existing search input. New and changed products are searchable in minutes, not after a nightly rebuild.
Every plan starts with 14 free days, no card. Growth is 999 kr a month for a single storefront and Scale is 2 999 kr a month for large catalogs and several markets. Overage is capped by a spend limit you control, and search never switches off because of billing.
