| Kai's verdict | S-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. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | A-tier in its niche. The only one that actually gets emotion right. |
