| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Best for teaching a kid to code in 2026. | A-tier in its niche. The only one that actually gets emotion right. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
