ShopBrain is an alternative to picking an offer's products by hand: instead of a fixed list, the offer's product source is handed to ShopBrain, which selects what to show per shopper from cart contents, customer context, and prior order history, optionally scoped to a specific collection so it never recommends outside a category you've approved.
Because the product selection is dynamic, a ShopBrain-powered offer's Smart Rules and behavior mode still apply exactly as they would to a hand-picked offer — targeting and discounting are unaffected by whether the product list is fixed or automated. What changes is only which product fills that offer's slot for a given shopper.
The AI Config tab on an offer is where you adjust how ShopBrain behaves for that specific offer, rather than being a global, account-wide setting — so two different ShopBrain offers can be tuned differently from each other.
