# Tutorial Plum Fuse is an interactive voice response (IVR) call-flow builder. Fuse employs a visual drag-and-drop interface that enables users to easily layout and connect the basic components of an IVR application. This tutorial will walk you through the tasks of building and deploying your first IVR application. This example demonstrates how Fuse collects and verifies user inputs, as well as how to use call-flow principles like branching logic, variables, and data integration.
