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

Bing Copilot Search

  • Built directly into widely used Microsoft products, requiring no separate signup
  • Provides source citations for verifying synthesized answers
  • One of the most widely distributed AI search experiences by sheer reach
  • Dedicated answer engines have iterated faster on citation quality and search-specific behavior
  • Built-in distribution doesn’t necessarily mean best-in-class search capability
  • Worth comparing directly against specialized AI search tools if search quality is the priority
