Pros & Cons

Slack AI

  • Basic AI summarization is included even at the more affordable Pro tier
  • Business+ provides genuinely valuable advanced features — natural-language search, recaps, translations
  • Deeply integrated directly into the existing Slack workspace, no separate tool needed
  • True AI search and other high-value features are strictly gated behind the pricier Business+ tier
  • Standalone lower-cost AI add-on was retired in 2025, removing that flexible pricing option
  • Pro tier’s AI capability is meaningfully more limited than Business+, which may surprise teams expecting more

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
