| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. | S-tier for open-source model APIs. The default in this space. |
