A method and system for providing an overlay window for an application to display augmentation data over the user interface of the application is provided. An overlay system includes an overlay component and an engine component that interface with the application and a presentation manager used by the application to provide the application window. When the overlay system starts up, it initializes the overlay component and the engine component. The overlay component tracks the portion of the application that is currently visible and displays augmentation data in an overlay window over the application window. The engine component provides augmentation functionality that generates the augmentation data and generates the overlay window based on the augmentation data. When the visible portion of the application data changes, the overlay component requests the engine component to generate the overlay window for the currently visible application data.
