About
LegitApp is a comprehensive luxury goods authentication service that pairs artificial intelligence with seasoned human expertise to verify the legitimacy of high-end products. Supporting 300+ brands across 11 categories—including handbags, sneakers, watches, streetwear, clothing, accessories, trading cards, toys, and collectibles—LegitApp has served over 2 million users and completed more than 3 million authentication cases worldwide. The platform's rigorous multi-layered process starts with dual AI analysis: LegitApp's proprietary in-house model and a specialized model developed in partnership with the Hong Kong University of Science and Technology (HKUST). Following AI review, at least two independent human expert authenticators scrutinize every detail of the submission. A dedicated review team then performs a final double-check within 24 hours before results are released. Users submit photos through the mobile app or web platform, select a preferred turnaround time (as fast as 10 minutes), and receive a clear AUTHENTIC or REPLICA verdict along with a free digital certificate of authenticity. This certificate serves as recognized proof on platforms such as eBay, PayPal, and for credit card dispute resolution. LegitApp is ideal for secondhand luxury buyers, resellers, collectors, and consignment businesses. A dedicated For Business tier supports high-volume authentication at scale, making it a trusted infrastructure layer for luxury commerce platforms.
