AntiScam Agent is an AI-powered mobile companion that protects second-hand marketplace buyers from scams before they pay. By analyzing the product listing, seller chat history, and a live video of the item, it gives buyers an instant, evidence-backed verdict on whether to buy, bargain, or walk away.

The Problem: Buying second-hand items from strangers means relying on a few photos and a chat, leaving buyers exposed to fake listings, overpriced goods, and deposit scams. Bank warnings alone don't stop people when they want a deal—buyers need real proof in the moment, not just another warning pop-up.

The Solution: Before handing over cash, buyers simply film the item on the spot using the app. The AI agent cross-checks the live video against the advertised photo, price, description, and seller conversation, then delivers a simple pass/fail checklist and a clear Buy, Bargain, or Scam recommendation in seconds.
