 Workflow Designer is a GUI-based utility which allows you to add AI logic to your web app, without actually modifying its source code. This makes your web app context-aware and therefore provides a better experience to your customers. For example, without updating the source code of your app, you can configure it to perform operations on voice instructions.
 
 This functionality is provided by an ecosystem that includes **Workflow Designer** and **Context Intent Manager (CIM)**. While Workflow Designer is used to define the workflow, CIM is used to execute the flow. The CIM component that is provided in the webOS image, interacts with the AI engine and the workflow to provide the required functionality. Check the video below for a basic walkthrough.
