GuruNet is a FREE new one-click information service that works whenever you're online. It automatically analyzes pointed-to text in context and pops up a simple window without linking or leaving your document. Just point and ALT-click on a word for reference information (e.g., dictionary, thesaurus and encyclopedia) and real-time information (e.g. news, sports, weather or stock quotes). Best of all, GuruNet works in any PC application, such as e-mail, MS-Office, PIMs and, of course, any browser.
Our Review: It's a dictionary, thesaurus, encyclopedia, web search engine, and translator all in one. And it's free, free, free!!! Forget about other search engine/online encyclopedias - use GuruNet.
