Pros & Cons
Perplexity AI
- Comet browser is now genuinely free worldwide since October 2025, removing a previous paywall entirely
- Education Pro’s $10/month rate provides meaningful savings for verified students
- Comprehensive tier structure (Free through Max, Enterprise Pro/Max) serves a wide range of usage needs
- Pro Search’s agentic reasoning mode carries separate request fees ($14-22 per 1,000 queries) beyond standard usage
- Max tier at $200/month represents a substantial cost for individual power users
- Enterprise Max at $325/seat/month is a significant investment for team-wide deployment
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
