Vypress Chat is a real-time communication and instant messaging solution designed for local area networks. It can be used as an intranet messaging system, an instant messaging system, a file-sharing program, or a combination of all three. It features private and public chat rooms, file transfers, voice conferencing, and server-based message archiving. It also supports multiple user groups and permission levels, allowing administrators to manage user access. It is compatible with Windows, Linux, and Mac OS X operating systems. Vypress Chat allows users to communicate quickly and securely with colleagues, friends, and family in a non-public environment. It is well-suited for corporate use, as it is highly secure and reliable, with no need for a dedicated server.
