Wordle Nyt was a very simple program that generated word clouds based on the frequency of words used in a given body of text. The newer version of Wordle, however, incorporates semantics, which means that it takes into account the meaning of words rather than just their frequency. This makes it much more accurate at generating word clouds that represent the content of a text.

Semantle is a similar program that gamifies the process of extracting meaning from texts. It does this by presenting users with a series of puzzles that get harder as they progress. Each puzzle requires the user to find a certain number of words that are related to a given topic. As users solve more puzzles, they unlock new features and earn points.

In the summer of 2010, Google Labs released a new web toy called Wordle. Created by Jonathan Feinberg, Wordle nyt today is a word cloud generator that allows users to enter any text, and create a visually appealing word cloud made up of the most frequently used words in that text.
