Watson Developer Cloud


Script conversations any way you like to answer questions, walk through processes, or just to chat! Note: The Dialog service is deprecated as of August 15, 2016. See its documentation for more information.


The IBM Watson Dialog service enables a developer to automate branching conversations between a user and your application. The Dialog service enables your applications to use natural language to automatically respond to user questions, cross-sell and up-sell, walk users through processes or applications, or even hand-hold users through difficult tasks. The Dialog service can track and store user profile information to learn more about end users, guide them through processes based on their unique situation, or pass their information to a back-end system to help them take action and get the help they need.

Intended Use

Walk a user through the steps to reset their password or help them choose a credit card. Developers script conversations as they would happen in the real world, upload them to the Dialog application and allow end users to get the help they need. This service should be used to enable back and forth conversations with a user. For example, clarifying questions, information gathering, walkthroughs and helping a user take an action.
