Pros & Cons

Kagi

  • Genuinely ad-free search results since revenue comes from subscriptions, not advertising
  • No annual lock-in — billing is monthly at every tier
  • Free trial (100 searches) allows testing before subscribing
  • Starter tier’s 300 searches/month cap requires upgrading for regular heavy use
  • Subscription cost is a real ongoing expense compared to free ad-supported search engines
  • Premium LLM model access requires the highest-priced Ultimate tier

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
