Kai's verdict	B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier for realtime. If latency matters more than voice catalog, start here.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
