Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier for designer-led sites. S-tier if animations matter.A-tier in its niche. The only one that actually gets emotion right.
