Google Translate is a service provided by Google to translate a section of text, documents or a webpage into another language. It is known for being inaccurate at times. For example, most of its popularity stems from its translations—which are not exact, but a major basis of incorrect English—often known as Engrish. For example, "The Google Wiki is the best wiki ever!" translates to "谷歌Wiki是有史以來最好的wiki！" which translates back to "Google Wiki is the best ever wiki!" (Notice that the words wiki and ever were swapped, and the was dropped.) It is also available on iOS mobile devices.
