GuruNet is a desktop-based application that gives you access to a rich resource of online information related to any word/subject you choose to enter into the application.
A tiny desktop bar is included that sits at the bottom right of your screen, letting you enter words immediately.
Alternatively, perform an 'alt-click' on any word in any program for immediate details on that subject.
This free edition only contains the dictionary and thesaurus options of the full application, but is still a good deal of use.
The dictionary definitions come courtesy of The American Heritage dictionary and the thesaurus details from Roget's.
Should you perform a typo the program will helpfully suggest corrections, rather than simply coming back with no results.
Search facilities are also included for retrieving results from various search engines, including Google and Alltheweb.
