Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-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.
