About Slack
Slack is a channel-based messaging platform that has become the default communication tool for millions of teams. It organizes conversations into public and private channels, direct messages, and threaded discussions to reduce email overload.
Key features include Slack Connect for cross-organization communication, Huddles for audio/video calls, Canvas for collaborative documents, Workflow Builder for no-code automation, and an app directory with over 2,600 integrations including Salesforce, Jira, Google Drive, and GitHub.
Slack differentiates itself through its integration ecosystem and the way it serves as a central hub connecting all the tools a team uses. The searchable message archive becomes an organization's institutional knowledge base.
Owned by Salesforce since 2021, Slack continues to expand with AI features including conversation summaries, search answers, and channel recaps.
