The open-source e-book management software Calibre has been updated to version 9.15. The new release introduces an optional AI-powered interactive writing game titled Create your own Adventure, which allows users to influence story progression through text input.
The feature is not enabled by default. Users must manually add it to the main toolbar via the Preferences menu under Toolbars and Menus to access the interactive writing tool.
The update also improves the highlighting panel, allowing users to select multiple highlights at once and apply uniform style changes via the context menu. Additionally, highlights containing notes now display a preview when a user hovers over them.
Interface improvements include a new window size toggle button in the sidebar. Users can now save and quickly switch between different window configurations. Furthermore, the cover grid settings have been updated to let users choose the corner position for cover badges.
