Wordle is a tool for generating word clouds from words that you type in; the more times you type in the word, the larger it will appear in your Wordle. You can create a Wordle without saving it to their gallery. See the websites FAQs for more information about Wordle.
Note to Parents: The website does not filter the language on Wordles that people create and post to their Gallery, so Parental Guidance is suggested when browsing the Gallery.
