This is a demonstration of Google's prediction API, a machine-learning service. Enter two or more different categories of text below and label them. For instance, put a paragraph of English text in the first data box and French text in the second. Label them English and French, respectively, enter your e-mail address (I promise I won't spam you), then hit the submit button.

A few moments later, you'll be able to start differentiating between the categories you've created using the Google Prediction API. If you follow the example above, for instance, you could enter a sentence and be told whether it's French or English.
