SDL FreeTranslation

Famous for its TRADOS software, SDL also provides free machine translations, but it does not offer a wide variety of translation services. You can only translate to and from English, and not other language pairs. To be able to use the advanced features, such as specialized dictionaries and translating more text, you must subscribe to its "Platinum Club" for $9.95. Though TRADOS is well-known and used by many translators, its free online service is unimpressive and it's probably best to go elsewhere.
