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

Ai2 Scholar QA

  • Answers are grounded in real, citable scientific papers rather than general model knowledge
  • Significantly speeds up early-stage literature review
  • Built by a respected nonprofit AI research institute with a research-specific focus
  • Synthesized answers should still be checked against the underlying papers for important work
  • Coverage depends on what literature is indexed and accessible to the tool
  • Not a substitute for deep, careful reading of primary sources
