## What the models said for it

- "many small companies use free Slack workspaces for community engagement. The free tier has limitations on message history, but it's a great starting point." (Claude Haiku 4.5, Community)
- "Use the free Slack tier for internal communication, or upgrade to Pro at $7.25/user/month for advanced features." (GLM 4.7 FlashX, Community)
- "Slack: A communication platform that can be used for building communities" (Llama 4 Maverick, Community)
- "you usually need a third-party middleware (like Slack integrations" (Qwen 3.7 Flash, Lead routing)

## And against it

- "Slack mined private conversation data within its messaging platform to train AI models without proper consent." (Qwen 3.7 Flash, Conversation intel)
- "useful for real-time chat, but they can be a poor fit when you need searchable knowledge, structured Q&A, moderation depth" (Perplexity Sonar, Community)
