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

ChatGPT

  • Largest user base and ecosystem of any AI assistant, with the most third-party integrations
  • Genuinely broad capability across writing, coding, research, and file analysis
  • Custom GPTs allow tailoring the assistant to specific repeated tasks
  • Frequent model updates keep it competitive on raw capability
  • Free tier has usage limits and access to a lower-tier model than paid plans
  • Can produce confident-sounding but incorrect information, especially without browsing enabled
  • Breadth can mean less depth than a tool purpose-built for one specific workflow
  • Data usage and training policies require attention for sensitive or regulated work
