Kai's verdictS-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.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
