About
Slack is a business communication and collaboration platform that brings team messaging, channels, huddles, file sharing, and workflow automation into one workspace. It is designed to help organizations coordinate work, share context, and connect people with apps, data, and AI agents.
The platform supports real-time conversations across internal teams and external partners, with tools for project coordination, document collaboration, and searchable workspace history. It also includes AI-powered capabilities such as Slackbot, conversation summaries, and enterprise search to help teams work faster and stay aligned.

- Audio and video huddles with screen sharing
- File sharing, canvases, lists, and templates for project work
- Workflow automation and app integrations
- AI features for search, summaries, and task assistance
- Security and admin controls for business use
Free Tier Value
The page is a free-tier comparison page, not a credit or trial offer, and it does not provide a concrete free-tier dollar value to convert. The free tier is clearly capped: 90-day message history, 1:1 huddles limited to 30 minutes, Clips, and integrations limited to 10 apps (the page also mentions 3 tools in one comparison block, but the extracted bullets specify 10 apps, so I use the extracted cap conservatively). Because the paid plan pricing is not shown as a concrete monthly amount on this page and is instead routed to pricing/contact flows, free_tier_value_usd_per_month is null.
What's included in the free tier
- Messaging with 90-day history, so you can access recent conversations.
- 1:1 huddles with audio, video, and screen sharing, limited to 30 minutes.
- Video clip recording with Clips for sharing updates.
- Integrations with other tools, limited to 10 apps.
