With Slack for Mac, you can create your own site where you work together with your team. Invite everyone who works with you and create specific channels, one for each topic or project. There, you can send and share text, links, and emoji, or you can attach documents directly from Google Drive. Actually, one of the most important features is the ability to upload files from tons of online tools, such as Dropbox, Google Drive, and Office 365 programs, making your life that much easier. You can also add audio notes or text with specific fonts and styles.
From the contacts menu, you can start a conversation with one or many people depending on what you need to discuss. You can also create channels for certain groups.

It also has a search engine so you can find anything you need by entering a keyword.
Slack centralizes your team's communication, helping you quickly access important documents and information concerning your project. It also has all kinds of tools to streamline tasks and plan work for groups or individuals.
