Pros & Cons

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

Brave Leo

  • Genuine privacy commitment — no conversation storage or logging after a response
  • Free tier includes access to several capable open models
  • Built directly into the browsing experience without switching tools
  • Only relevant to Brave browser users, not a standalone product
  • Premium models require a $14.99/month subscription
  • Not a strong reason on its own to switch browsers if privacy isn’t already a priority
