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
Meta AI
- Genuine free access remains available (25-50 prompts/day) even after introducing paid tiers
- Integrated directly into widely-used apps (WhatsApp, Instagram, Facebook) rather than a separate app
- Meta One tiers provide a range of options from $7.99 to $499 depending on needs
- Daily prompt limits (25 logged-out, 50 logged-in) restrict heavy free usage
- Paid tiers were introduced specifically due to rising infrastructure costs (68% YoY increase in Llama hosting), suggesting continued cost pressure
- Business Agent bills separately by token usage ($2.00/million tokens) starting August 2026
