Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier in its niche. The only one that actually gets emotion right.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
