| Kai's verdict | A-tier in its niche. The only one that actually gets emotion right. | S-tier in its category. The first AI music tool I'd actually listen to. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. |
