WordSift is a useful tool that allows users to easily sift through text and quickly identify key words. Simply cut and paste any text (65 K limit) into the WordSift textbox. Within seconds, WordSift will create a word cloud based on the fifty most frequent words that appear in the text. The word cloud displayed is not static. WordSift allows users to sort the words in the cloud via common to rare, rare to common, A to Z, and Z to A.
Select any word in the cloud, and WordSift will display a visual thesaurus and provide a Google search for images and videos.
