Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for designers. The only one that takes vectors seriously.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
