In the right column under "AI & Keywords", Excire's own keyword hierarchy and the hierarchy of user-defined keywords are displayed one below the other and can be expanded and collapsed.

In the Excire Foto keyword hierarchy, only the keywords that have already been assigned to one or more photos during the analysis are displayed. It is not a complete list of all keywords available in Excire Foto.
The Excire Foto AI keyword hierarchy cannot be modified by the user.
The situation is different with the user-defined keyword hierarchy. Here, any number of keywords can be added and created in the form of a custom hierarchy.
Important: A user-defined keyword hierarchy must be created in advance before the keywords are assigned to photos. Once keywords have been created, they cannot be subsequently arranged in a hierarchy.
To add a keyword to the user-defined hierarchy, right-click on an existing keyword and select "Create keyword". The new keyword will then be placed under the selected keyword in the hierarchy.
