ConstEdit is a word processor useful for your daily work, and personal needs. It is not a cloud app and is not an online html editor. It runs locally on your pc for better performance, convenience and security, while providing more functionality.

Interoperability. ConstEdit writes documents in the standard internet webpage format (html/htm file extension). You do not have to install any particular software to read the html documents generated from ConstEdit, not even ConstEdit itself. Just your favorite browser will do, in any common computer operating system (not all style formatting properties used in ConstEdit are supported by all web-browsers).

Separation of content from presentation/formatting. By making use of external Cascaded Style Sheets CSS, there is no more need to worry about styles formatting while you are editing the document content. E.g. when you insert a new section, the new section is already rendered with the designed style with the correct outline numbering on it; or when you demote a main section to becoming a sub-section, the numbering on the section title is updated immediately and the section is reformatted as a sub-section.

User interface. ConstEdit ui is simple and intuitive with multi-tabbed file editing.

Section outlining. ConstEdit allows you to visualize and manage the document sections structure easily with drag and drop without doing any cut and paste. Novelists may find this feature particularly useful for designing their storyboards.
