Slack is a private messaging network designed so that workers of the same company can share information with each other privately as if it were a conventional social network. This group chat has a very simple interface and a mode of use similar to any other tool of the style, so that no one will have problems when accessing all its functions.
With Slack, all team members can send and receive all kinds of relevant information and mention specific people to prevent them from seeing the message between the conversation. On the other hand, this tool is synchronized with the services of Dropbox, Tello or Google Drive, facilitating in this way the sending and access of files that we have stored in the cloud and that we need to share with our colleagues without having to navigate between the applications.
Slack also offers a JIRA technical service and other tools such as statistics or video conferencing with Hangouts. In addition, as it does not have a limit of users, no matter the size of the company, all its workers will be able to keep up with this corporate chat at all times.
