Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.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.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
