Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
