AskJot (formerly SemantalyzR) is an easy to use tool for analyzing web pages for semantic data. On our page analysis you'll find keyword links to search pages for that keyword. These search pages are made up from results of various services on the web. 

The easiest way to use AskJot is to add our bookmarklet to the bookmarks toolbar of your browser. Then, whenever you are at a page on the web you'd like to analyze, just click the AskJot bookmark and it will take you to an analysis page for that page.

(right-click here... AskJot and save this to the links section of your bookmarks)
