Open Shelf: your PayPal shop, ready for AI shoppers. See a demo store

Your PayPal shop.
Ready for AI shoppers.

Open Shelf turns what you already sell on PayPal into a store AI agents can search, question and buy from. Your store gets its own agent that answers from what you published, and every sale is a PayPal order the buyer approves.

How it works

From PayPal to AI shoppers

Three steps, and nothing for you to host.

Bring your PayPal shop

Log in with PayPal, then import your payment links and invoices, a Shopify store, any product page or a price list you paste.

Your store agent answers

Shoppers’ AI agents ask about fit, ingredients and shipping. It answers from what you published, and asks you when it doesn’t know.

Sold through PayPal

The buyer approves every order in PayPal. Tracking goes back to PayPal, refunds follow your policy, and Channel3 lists you everywhere.

After the sale

Paid, shipped, refunded

Every order is a PayPal order in your account. The rest of the sale runs from the same place.

01Tracking to PayPalAdd a tracking number and PayPal and the buyer get it. Agents read it back with order_status.
02Refunds in policyInside your window, a shopper’s agent gets an instant PayPal refund. Outside it, you decide.
03Questions inboxWhat your store agent couldn’t answer waits for you. Answer once and it knows from then on.
