Babylon is a complete dictionary and translation solution, perfect for anyone who frequently works with multiple languages.
Babylon works from various aspects. The main interface is a translation window. From here you can access all the program features, as well as the configuration options. There is also a floating module which will appear when you ask Babylon for a translation. The whole module can be disabled if you want.
No matter which option you use, Babylon provides access to a standard multi-lingual dictionary (to which you can add an unlimited number of additional dictionaries), a text/document translation feature, a unit converter, web search and, of course, access to Babylon's paid translation services.
