Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
