Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for designer-led sites. S-tier if animations matter.
