ProofTag

ProofTag is a mobile + web AI-assisted tool that helps secondhand sellers create “trust packs” for each clothing item: condition grading, measurements, fabric/care label capture, and a simple authenticity/brand-consistency check. Instead of trying to be another marketplace, it plugs into where people already sell (Poshmark, Depop, eBay, Vinted) by generating a shareable listing page and exportable description/photos. The app guides sellers through a fast capture flow: take 6 required photos, record key measurements, and answer a few prompts. It then produces a standardized condition score, highlights flaws with annotated images, and creates buyer-friendly disclosure text. Buyers can scan a QR code from a listing to view the trust pack, reducing “item not as described” disputes. Monetization: subscription for power sellers plus per-item trust pack fees.
