Tumult HyperEdit is an HTML editor used for typing text that will be published on websites. The program's unique feature is its ability to display how the code affects the website while typing. It is as if the user is typing on the website, and not on the HTML editor. In this way, there is no need to type HTML codes on a text file, save it, and then reload the file on the browser. Also, through this application, the changes are seen immediately, even before the HTML texts are saved. This eliminates the time it takes to write the code on a separate editor and then opening another window or tab to preview the changes that have been made.
