| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | A-tier for social/casual. B-tier for serious work. Good entry point. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. |
