Microsoft Cognitive Services provides a set of cloud-based APIs with functionality that brings more of a human element to your app’s interaction through vision, language, knowledge, and search.
One of the advantages of these cloud-based APIs is that they can be used regardless of the client platform and so can be applicable both to you, as a UWP app developer, but also to a website developer and to a developer who’s wanting to build cross-platform native apps using technologies, such as Xamarin.
