## Key features

- **Channels and direct messages:** Conversations are organized into channels for each project, topic or team, alongside direct messages. Paid plans keep the full message and file history searchable; Free keeps 90 days.
- **Huddles and clips:** Huddles are audio and video meetings with screen sharing, 1:1 on Free and for groups on paid plans. Clips are recorded audio or screen updates shared in a conversation.
- **Slack Connect:** Message people outside the company. Free allows 1:1 external direct messages; paid plans add group chats and shared channels with up to 250 organizations.
- **Canvases and lists:** A canvas holds text, files, images and video inside Slack, and lists are used to manage projects and organize tasks with teammates.
- **Workflow Builder and apps:** Workflow Builder automates routine processes without code, and the app directory lists more than 2,600 apps. A Free workspace can connect up to 10 of them.
- **AI in Slack:** Pro includes AI conversation summaries. Business+ adds AI search, daily recaps, file summaries, workflow generation and the Slackbot personal agent, subject to plan limits.

## Good for

- Teams that want conversations organized by channel rather than email threads
- Companies that work with outside partners in shared channels
- Organizations that already run on Salesforce
- Teams that connect many third-party apps to their chat

## Worth knowing

- The Free plan keeps only 90 days of message history searchable, allows 10 apps, and limits huddles and Slack Connect to 1:1.
- SAML single sign-on and SCIM start at Business+; ongoing Slackbot access is on Business+ and Enterprise+, with a limited trial on Free and Pro.
- Enterprise search, multiple SAML configurations and native data loss prevention are limited to Enterprise+, which is priced by sales.
- In a browser, huddles are supported only in Chrome and Firefox.
