AI Counterfeit Detector

This tool, available for free on Yiaho, allows you to quickly check an item’s authenticity simply by uploading a photo. It analyzes details that are hard to spot with the naked eye and gives you an initial assessment before a purchase, resale, or collection check.  

The goal is to make expertise accessible to everyone, without registration, without contact, easily and in seconds.

How the AI analyzes your item

The AI inspects the visual elements that usually distinguish an authentic product from a counterfeit. It checks material quality, texture, stitching regularity, logo precision, pattern consistency, shades, metal finishes, serial number appearance, symmetry, and proportions.  

It can also spot common errors in copies, such as leather that is too smooth, approximate typography, or misaligned details.

What you need to send

The analysis works with a single photo, but it becomes more accurate if you send several. For bags: logo, inner label, stitching, texture, corners, handle, closure. For watches: dial, crown, engravings, strap, buckle, case back, numbers. Each image helps the AI compare the item with the characteristics of an authentic model to spot inconsistencies.

What result you receive

The tool provides a confidence score along with a list of observed signals. It explains what seems consistent with a real model and what appears suspicious. If important elements are missing, the AI tells you clearly and suggests which photos to add for a more reliable analysis. The goal is to give you a simple and useful overview, without technical jargon.

Online Counterfeit Detector: Limits to Know

Even though the AI is very powerful, it does not replace an official appraisal or a professional certificate. Some rare or very old models require a more in-depth inspection.  

The tool is mainly used to spot early warning signs or confirm an impression. It is a practical visual assistant, but it cannot guarantee 100% authentication.

Why is this tool useful?

The second-hand and luxury market attracts more and more buyers, but also many copies. This tool helps you avoid unpleasant surprises by giving you a quick, accessible, and independent opinion. It is designed to be simple, transparent, and usable directly from your phone, without an account, registration, or photo storage.  

It allows you to save time, reduce risks, and better secure your transactions.
