A meta-application is a software program that serves as a platform for other applications to run on. It acts as a central hub, providing a framework and tools for developers to create and integrate various applications, making it easier for users to access and manage multiple programs in one place. Unlike traditional applications, a meta-application does not have a specific function or purpose, but rather serves as a versatile and customizable tool for organizing and optimizing the use of other applications. It allows for seamless communication and collaboration between different programs, enhancing overall efficiency and productivity. In essence, a meta-application is the ultimate multitasking tool, simplifying the complex and diverse world of software applications.
