Slack is a work collaboration platform that brings conversations, tools, and information together in one place. Its core features include channels for organizing team discussions, direct messaging, audio and video huddles, recorded clips, and shared files. Teams can also use Canvas for flexible documents and Lists to track projects and tasks.

Slack’s platform connects with business apps and services, while Workflow Builder helps automate everyday processes. Its AI features include Slackbot, a personal AI teammate that can search Slack history, connected apps, and the web; prepare meeting materials; analyze information; draft content; and help create reports, dashboards, and repeatable workflows. Slackbot can also take actions across connected apps, including Jira, Figma, Salesforce, and DocuSign. For small businesses, Slack CRM supports customer management tasks such as updating records, logging calls, and preparing follow-ups.

Additional offerings include enterprise search, security and access-management tools, Slack Marketplace apps and agents, templates, and resources for teams across departments and industries.
