Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier for designer-led sites. S-tier if animations matter.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
