Independent overview
What Slack is designed to do
Slack is a workplace communication platform for channels, direct messaging, files, calls, canvases, workflows and integrations. It is commonly used as the real-time communication layer between teams and the software they use every day.
The free tier is suitable for smaller groups with limited history, while paid plans expand history, collaboration, administration, security and AI-assisted workflows. Organizations should evaluate notification load, retention policies, guest access and integration governance before making Slack the default communication hub.
