Weaknesses
- -Free plan limits message history and allows only a limited number of app integrations
- -Notification overload in large workspaces, channels can become noisy without discipline
- -Pricing adds up quickly for large teams
- -No built-in project management, still requires separate tools like Asana or Jira
- -Slack AI features require higher-tier plans, not available on all plans
