About Slack
Slack is the enterprise team communication platform that replaced email for millions of workers. Organized into channels for projects, topics, or teams, Slack keeps conversations searchable and accessible. The 2025 platform bundled all AI features into the Business+ tier, adding AI-powered summaries, search, and automation. With 7,000+ app integrations, Slack becomes a central hub connecting your entire workflow. While the free tier limits message history to 90 days, paid plans unlock unlimited history, advanced search, and group video calls. For distributed teams, Slack's real-time messaging, threads, and emoji reactions create the digital watercooler that keeps remote culture alive.
