From the developer:
Jin Writer is an application for novel creation. The files interface is used to manage your documents, but it is also a cloud disk. When you edit a document, the chapter interface automatically identifies words like 'Chapter 1' that appear in the document, automatically displays them in a list, and displays the number of corresponding words.
