Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
