Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for model-shopping. I use this for every prototype before committing.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.
