| Kai's verdict | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier in its category. The first AI music tool I'd actually listen to. | A-tier if you already pay Gemini. B-tier standalone. |
