About Slack

Slack is an AI-powered work platform that brings together people, tools, and agents to streamline collaboration and productivity. It replaces email with channels—organized spaces for conversations around teams, projects, and topics. Slack includes Slackbot, a personal AI agent that summarizes conversations, searches across files and apps, generates workflows, and provides daily recaps. It also offers huddles with AI note-taking, Slack Connect for secure external collaboration, and over 2,600 integrations with apps like Salesforce, Google Drive, and GitHub. Automation is built-in with Workflow Builder for no-code routines, and Slack Lists and Canvas help manage projects and share knowledge. Enterprise-grade security, including SAML, SCIM, and data loss prevention, supports compliance. Slack is used by over 200,000 paid customers, including 77 of the Fortune 100, and claims users save an average of 97 minutes per week with its AI features.
