The tool allows for the retrieval and re-insertion of previously copied items and text snippets into active application windows. It monitors the operating system for clipboard change events to automatically capture and store new data.
The system utilizes a local database for persistence and indexing, enabling the storage of formatted text and binary image data across sessions.
