Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
