| Kai's verdict | 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. Bet on this one — the Sparkpage format is genuinely new. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
