Vitrina is a closed-loop AI storefront for small sellers in Colombia who run their business on WhatsApp. A seller working alone has no ad designer, answers every chat between orders and deliveries, and never learns which ad actually sold.

With Vitrina, one phone photo becomes ad scenes, and a fidelity verifier blocks any scene that changes the real product. Each approved ad gets a code (#A7) and a WhatsApp link, so every chat is tied to the ad that started it. A sales agent answers only from the seller's catalog and cites its facts. Rules outside the model check every reply, and anything it cannot prove, like a haggle, goes to the owner with a summary. Promotions reach only customers who consented (Ley 1581), inside legal hours (Ley 2300). Each week, the objections and the attribution become the next ads.

Everything customer-facing is in Spanish. It was built during the hackathon and it is live: https://vitrina.alinedlabs.co. Ten-minute judging guide: https://github.com/alined-labs/vitrina/blob/main/JUDGING.md
