With the PredictionIO Android SDK, users can integrate prediction features into web and mobile applications. The API is about machine learning services for developers and data scientists who are interested in building prediction projects. According to the main site, developers like this service because is customizable and scalable, while data scientists prefer the service because it provides an interface for analysis and evaluation of parallel models.

The ŷhat Cloud Toolbox is a suite of development tools for integrating predictive analytics into existing Web and mobile applications. ŷhat deploys your models as RESTful APIs, so there's no need to port, translate, or adapt models for integration with existing systems. It is currently in beta testing and an invite only stage.
Google is shutting down the Cloud Prediction API on April 30, 2018. After this date, the API will no longer be accessible. The company is recommending developers migrate applications to the Google Cloud Machine Learning Engine, a managed service that can be used to build machine learning models.
