Weaknesses
  • Expensive
  • Best for well-scoped tasks
  • Not for solo hobbyists
  • Still hit-or-miss on complex multi-hour tasks

  • Less flexible than raw code
  • Pricing per-site adds up
  • Image generation is weak

Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier for designer-led sites. S-tier if animations matter.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
