About
Slack is a business communication and collaboration platform that brings team messaging, channels, huddles, file sharing, and workflow automation into one workspace. It is designed to help organizations coordinate work, share context, and connect people with apps, data, and AI agents.
The platform supports real-time conversations across internal teams and external partners, with tools for project coordination, document collaboration, and searchable workspace history. It also includes AI-powered capabilities such as Slackbot, conversation summaries, and enterprise search to help teams work faster and stay aligned.
- Organized team communication through channels and direct messaging
- Audio and video huddles with screen sharing
- File sharing, canvases, lists, and templates for project work
- Workflow automation and app integrations
- AI features for search, summaries, and task assistance
- Security and admin controls for business use
Free Tier Value
This free tier is a capped but genuinely usable starter offering: it includes 90 days of searchable history, one workspace, limited apps, basic AI, and 1:1 collaboration, but it stops short of the paid plans’ unlimited history, broader external collaboration, and stronger admin controls. With Pro starting at $8.75 per user/month, the free tier feels worth roughly a third of that - about $3/month - because it covers core day-to-day use while leaving the main power features behind.
