Capsule is a system that packages HTML-based applications and their data into a single file with the .capsule extension. Its key feature is that it can be used offline without requiring cloud services or account registration. The desktop version is available for Windows, macOS, and Linux, with plans for Android and iOS support in the future.
Regarding its internal structure, in addition to the HTML and related assets that constitute the user interface, user-inputted data (including images and PDFs) is saved as an SQLite database within that single 1 file. By sharing the file via email or AirDrop, the recipient can open the application including all saved data, provided they have the Capsule software installed.
Users can utilize any AI assistant to create applications. By describing desired functions and interfaces to an AI, it is possible to have it assist in the design of applications that can be handled by Capsule.
While a network connection is not required to use basic functions, it is possible to incorporate features that use local or remote AI models within the application. Note that since the application cannot access the device's file system directly, permission is required for internet connectivity.
