One Hour Translation has launched a free online machine translation detector. Translator Detector is the only automated tool on the web that can determine whether or not a given text was machine translated.

The way it works – Simply enter the source and translated text. The Translator Detector will automatically identify the source and target language. The translator detector will then automatically translate the source text using the three most common Machine Translation tools: Google Translate, Yahoo! Babel Fish and Bing translator. The resulting machine translated documents are then compared to the existing translation. The overall probability that the text was translated by a Machine is presented graphically.
