A computer-implemented environment for creating, curating, sharing and storing document contents in a concise, structured, modular, standardized and story-like format. The environment enables users to define content with a set of Cards, and arrange, connect and disconnect Cards so as to define a distinct Story. The environment additionally provides a user-adjustable Card content separator configured so that content below the separator is not instantly visible to the user. Furthermore, the environment enables the automatic conversion of files, data feeds and search results into Cards and Stories.
