The Paraphrase Tool – for Mac / OS X
If you need to pare down text on mac os x, you might want to try the Summary Service. You can select text from most applications (Safari, Text Edit, etc) and then choose the apple menu, services, and then summary. If the application you are using doesn’t support services, copy the text to a TextEdit document to get a summary.
