New products are available in the Quiz Builder's product search immediately after being created in Shopify. Products are fetched on-demand from the Shopify Admin API whenever you search in the builder or generate a quiz — there is no sync delay.
New products are not automatically added to existing quiz results — you'll need to manually assign them to the appropriate terminal options in the builder. This ensures your quiz recommendations stay intentional and accurate.
When you expand your catalog significantly, consider using AI Generation to create a fresh quiz that incorporates your new products automatically.
