| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Bet on this one — the Sparkpage format is genuinely new. | S-tier in its category. The first AI music tool I'd actually listen to. |
