Slack is an online social messaging platform designed for teams of all sizes to collaborate more effectively on projects. Users can create a Slack team and then log in to have group or private chats, exchange data and links with each team member, and discuss the project together.

Slack organizes team conversations into open channels. The great thing about using channels is that anyone can use them; all users have a transparent view of all its aspects.

If you have sensitive information to discuss, users can create private channels and only invite a few team members. Private channels are restricted and no one else can see or join the private channel.

A really useful feature of Slack is the ability to share files. You can drag and drop files, documents, PDFs, images and videos to share with anyone and get immediate feedback and discussion through comments. You can also mark it for future reference and all data is fully searchable. Slack also supports services such as Google Drive, Dropbox, and Box. Just paste the link to the file and that document will be instantly synced and searchable.

All data in Slack is automatically indexed and archived so that it can be found. Be it messages, notifications or files. Slack indexes the contents of each file so you can search for data stored in PDFs, Word files, and other documents.
