| Kai's verdict | A-tier. Genuinely different vibe from Suno — worth trying both for a month. | S-tier for solo + free. The best free option, hands down. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
