About Slack
Slack is a messaging hub that replaces email for millions of teams. Conversations are organized into channels—dedicated spaces for projects, teams, or topics—so everyone stays aligned. With native AI features like conversation summaries, Slackbot (a personal AI agent), and AI-powered search, Slack helps teams work faster and smarter.
Who is Slack for?
Slack is built for remote, hybrid, and in-office teams of any size. It's especially valuable for engineering teams connecting code repos and CI/CD alerts, sales teams tracking deals with CRM integrations, and any organization that needs async communication across departments. It's less suited for very small teams that don't collaborate externally or rely heavily on email.
Key capabilities
Slack connects over 2,600 apps (Salesforce, Jira, Google Drive, ChatGPT, and more), supports huddles for instant voice calls, and offers Slack Connect for secure collaboration with external partners. Workflows and Lists let you automate routine tasks and manage projects without leaving Slack. With AI features like daily recaps, file summaries, and meeting notes, Slack turns conversation data into actionable insights.
Use cases
Use Slack to launch products with cross-functional channels, run stand-ups, automate approvals, chat with clients in real time, and keep your team's entire history searchable. It's trusted by companies like Anthropic for scaling alignment and speed.
