Kai's verdict	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier in its category. The first AI music tool I'd actually listen to.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	S-tier for builders. The right primitives. What Kai is built on under the hood.
