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 its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.
