| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. | S-tier in its category. The first AI music tool I'd actually listen to. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
