Build AI agents for everyday work


Where work happens
Team messaging and collaboration hub with channels, huddles, and integrations.
A team messaging platform organised around channels, with huddles, canvases, workflow automation, AI features and a large app ecosystem.
Slack is a messaging platform for teams, organised into channels for topics, projects and groups, with voice and video huddles, document canvases, automation and thousands of app integrations.
Slack centres team communication on channels, keeping conversations organised by topic, project or team rather than in individual inboxes. Huddles provide quick voice and video calls, canvases hold shared notes and resources, and Workflow Builder automates routine tasks without code.
Slack AI is now bundled into paid plans: basic AI features such as search and recaps are included on all paid tiers, and advanced AI features sit on Business+ and above. The app directory connects Slack to thousands of tools, and it integrates tightly with Salesforce, its parent company.
Pricing is per active user under a Fair Billing Policy, so you're only charged for members active in a rolling window. The free plan has no seat limit but keeps only 90 days of message history. Pro adds unlimited history and apps, Business+ adds compliance and advanced AI, and Enterprise+ (formerly Enterprise Grid) serves large organisations.
