These applications will help users keep tracks of the number of words they have in a paragraph, the whole document or in a selected segment.
One can rely on these software utilities to perform automatic word count, character count, line count or page count, as well as word frequency.

Even though this function is usually included within complex word processors, there are also numerous standalone tools that perform only word counting.
