Outliner

Type of software to organize texts

An outliner is a specialized type of text editor used to create and edit outlines, which are text files which have a tree structure or a tree view, for organization. Textual information is contained in discrete sections called "nodes", which are arranged according to their topic–subtopic (parent–child) relationships, like the members of a family tree. When loaded into an outliner, an outline may be collapsed or expanded to display as few or as many levels as desired.
