Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier. If you're on Vercel/shadcn, this is cheating.A-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.
