Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. S-tier if you self-host. The reason open-source image gen matters.
