Non-limiting examples of the present disclosure relate to creation and management of exemplary notecard items that are reusable in different contexts and across different applications/services. Exemplary notecard items may be created and presented through a user interface of an application/service. A notecard item is individual, self-contained digital data object that provides content to supplement a digital document. Exemplary notecard items live outside of an application/service, in which the notecard item is created or used, where a notecard item may be linked to a digital document but also exists as a separate object. For instance, an exemplary notecard file may be created for management of a created notecard item, where the notecard file is stored in one or more data storages (e.g., a local cache of a computing device and/or a distributed data storage) that is accessible by applications/services.
