Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for teachers. If you teach K-12, start here this week.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
