Weaknesses

  • Slow vs doing it yourself
  • Breaks on complex auth flows
  • $200/mo gate

Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Still early. Manus is more flexible for less money.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
