Kai's verdictS-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. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
