Weaknesses
  • Terminal-based — learning curve

Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
