Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
