Duo Mentis

Small merchants in India struggle to market their businesses because existing AI tools are expensive, English-first, and difficult to use. During this hackathon, we built Vyapari, an AI platform that helps local merchants create personalized marketing campaigns using natural voice interaction. The merchant simply shows their shop and product through the camera and speaks in their native language. Our multimodal pipeline creates a Brand Brief, and using NB2 Lite, we explore 10 marketing campaign strategies in parallel instead of generating just one advertisement. The AI automatically evaluates every campaign and selects the best one. Unlike existing tools that rely on templates or AI avatars, Vyapari creates advertisements featuring the merchant and their own product. The selected campaign is converted into a video advertisement using Omni Flash, personalized for customers, delivered through WhatsApp, and printed with a real UPI QR code. Unlike existing tools that stop after generating content, Vyapari doesn't stop until a real customer makes a purchase.
