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

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
