| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier. Best for fast prototypes. Competitive with Lovable — try both. |
