TinEye is a powerful reverse image search tool using computer vision and machine learning technology. It offers a variety of products and APIs for different situations, including image tracking, content moderation and fraud detection. That means it can be used in a variety of contexts, including e-commerce and digital media.
Another good option is Score, a browser extension that performs instant reverse image searches to match or find similar products. It taps into trusted retailers like Google and Bing, factors in shipping costs, and doesn't sell your data for advertising purposes. The free version has a limited number of searches, but Score Pro offers unlimited searches and other features for a few dollars a month, which could be worth it if you're an online shopper.
If you're a developer who wants to build image recognition and visual search into your app, Ximilar offers an AI-based service. You can create your own models, embed them into your own system and use machine learning to spot objects in photos. It's geared for e-commerce, fashion and other businesses that need to automate image processing and search.
