Select - click - read. That's how easy it is to use one of the most popular tools currently available on the World Wide Web. The underlying concept behind Mr. Check is ingenious and simple. Partner websites that have implemented the application can, at the click of a button, access the wealth of terms and definitions contained in selected dictionaries and reference works (such as Duden and Brockhaus). Thanks to the iq-engine, the query and response process takes place within a fraction of a second, with outstanding results. The Mr. Check team managed to complete the programming in just four weeks.
