About RepCheck

The global counterfeit goods market is estimated to be worth over $500 billion annually. From replica watches sold as genuine on online marketplaces to counterfeit handbags passed off at consignment stores, the sophistication of fakes has reached a point where even experienced collectors can be deceived.

Traditional authentication services are expensive (often £30–£150 per item), slow (3–10 business days), and require you to physically ship the item. For most buyers, that's simply not practical — especially when you're standing in front of a seller or browsing listings online and need a quick sanity check before committing.

RepCheck uses advanced AI vision models trained to recognise the visual markers that distinguish genuine luxury products from replicas. Our system analyses hundreds of data points in every photo — stitching patterns, hardware engravings, logo proportions, material textures, serial number formats, and more — cross-referencing them against a comprehensive database covering 5,000+ brands and 10,000+ reference models.

The result? A detailed authentication report in under 10 seconds, accessible from any device, for a fraction of the cost of traditional services.

RepCheck is powered by state-of-the-art AI vision models capable of analysing luxury products at a level of detail that rivals trained human authenticators. Our proprietary authentication database includes:

• Detailed specifications for 10,000+ genuine reference models
• Known tells and characteristics of 25+ replica factories
• Stitching patterns, hardware specifications, and serial number formats
• Material composition and finishing standards by brand and era
• QC (quality control) grading for identified replica sources

Our database is continuously updated as new models are released and replica manufacturing techniques evolve.

We believe in transparency. RepCheck is a screening tool, not a replacement for professional authentication. We clearly communicate the limitations of AI-based visual analysis and always recommend in-person verification for high-value purchases. We don't store your images, we don't share your data, and we use 256-bit encryption for all communications.

Our mission is to make luxury authentication accessible to everyone — whether you're a first-time buyer checking a watch on eBay, a seasoned collector screening consignment stock, or a reseller verifying inventory.
