| Kai's verdict | S-tier in its category. The first AI music tool I'd actually listen to. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
