Word Counter for Mac

From SuperMagnus Software:

Word Counter is a Macintosh OS X application that performs a word count and a character count, but it can do much more. It can be used independently or in conjunction with other applications such as TextEdit, Microsoft Word, Pages, TextWrangler, and others.

Text can be typed, pasted, or dragged into the window. Word Counter can automatically update the count based on a user-defined time interval. It can show the progress achieved towards a set goal for the total number of words and characters. It also can perform bulk counts on multiple files and folders simply by dropping them onto the window. Word Counter can count the number of times a particular word appears in a document. It can even create a sortable summary table of all words in the document, with the number of times each word appears and the length of each word.

Word Counter can handle various file types including plain text (txt, text), rich text (rtf, rtfd), Hypertext Markup Language (htm, html), Microsoft Word (doc), Microsoft Word XML (wordml), Apple's web archive (webarchive), and others. This program may be useful for writing a manuscript or an abstract with a strict limit on the number of words or characters allowed.
