Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-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.
