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
