Visual Vocabulary

I have previously mentioned various visual dictionaries/thesauruses. Here is an interesting addition to Visual Thesaurus. VocabGrabber analyzes any text you're interested in, generates a list vocabulary words and shows how those words are used in context.
All you have to do is copy & paste text into the box, and then click on the "Grab Vocabulary!" button. Then, a vocabulary list that you can sort, filter, and save is automatically created. If you select a word on the list you can see a snapshot of the Visual Thesaurus map and definitions for that word and examples of the word in your text. They also provide sample texts (including the US Bill of Rights) so you can see how it works.
