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 for real-time. B-tier for everything else. Worth checking when news breaks.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
