Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier in its category. The first AI music tool I'd actually listen to.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for data teams. S-tier if you already live in SQL + Python.
