Assistant

The IBM Watson™ Assistant service combines machine learning, natural language understanding, and integrated dialog tools to create conversation flows between your apps and your users.

Usage

You complete these steps to implement your application:

• Configure a workspace. With the easy-to-use graphical environment, you set up the dialog flow and training data for your application.

• Develop your application. You code your application to connect to the Assistant workspace through API calls. You then integrate your app with other systems that you need, including back-end systems and third-party services such as chat services or social media.

Message

Send a message to the Assistant instance

}
