Word Welter is a free Chrome extension developed by Ben Smith. It falls under the category of Browsers and is classified as an Add-ons & Tools program. The main purpose of Word Welter is to demonstrate typoglycemia, a cognitive phenomenon related to reading written text.

The extension scrambles the characters in all words on a webpage, except for the first and last characters. This scrambling code is designed to handle various types of words, including those with punctuation and apostrophes. However, it is important to note that Word Welter is not a comprehensive text parser and may have some limitations.

By scrambling the text, Word Welter aims to showcase the cognitive processes behind reading and comprehension. Despite the scrambled text, most people can still understand the meaning of the words, as demonstrated by the example provided in the extension's description.

Word Welter offers a unique way to explore the cognitive aspects of reading and can be an interesting tool for those interested in linguistics or cognitive psychology. If you encounter any issues or have suggestions for improvement, the developer encourages users to provide feedback.
