Pros & Cons
Perplexity Comet
- Genuinely free browser with no account required for basic use, following the October 2025 pricing reversal
- Perplexity Pro subscribers get Comet Plus included at no extra charge
- Available across Mac, Windows, iOS, and Android for broad accessibility
- Was originally a $200/month Max-only product before going free just four months later
- Autonomous Background Assistants require the substantial $200/month Max plan
- Premium publisher content requires the additional $5/month Comet Plus subscription
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
