Can the AI add products to a customer's cart?

Yes. Mid-conversation, the assistant can edit the customer's cart directly, so a shopper sorting out what to buy doesn't leave chat to fix line items by hand.

The four operations

• Add items to the cart from the conversation.
• Update quantities on a line item.
• Remove products the customer no longer wants.
• Clear the cart entirely for a fresh start.

Those cover what customers typically ask for once they're talking to support with a purchase in progress.

Where the edits apply

On the storefront, cart changes work while the customer shops your site. On Shopify Plus stores, they also work during checkout, not only before it starts, so you can still help with line items late in the purchase flow.

Stores not on Shopify Plus get the storefront behavior; the during-checkout part is a Plus capability.

What the customer sees

The change lands instantly in their browser. No manual re-adding, no refresh dance; support and checkout stay in sync with what was agreed in the conversation.

That immediacy is what makes cart editing a conversion feature rather than a novelty. The shopper asks, the cart updates, and the purchase keeps moving.
