Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
