This is writely. It uses a predictive text algorithm to generate new text based on a sample. Basically, it gives you random sentences related to the original thing. Paste in song lyrics, scripts, books, essays, or speeches and get hilarious new results!
Hint: If you click "writely" when it's in the middle of the screen at the beginning, it automatically opens the prediction window. Thanks to the great statistician Andrey Markov for inventing the Markov chain.
