This reduces the duration of time and efficiency in work. To solve this problem, a web-based chat application was designed. Because the development of these applications must use a good and structured design. Web-based chat application was created to solve this problem. This web-based application can be accessed via a web browser without having to install the application on a cellphone or laptop user. Based on the design of a web-based chat application that has been created, it is expected to be a solution for discussing, communicating and sharing files between employees in a company. In addition, it is useful to keep in touch and share files without having to install applications on cellphone or laptop users.
