| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier for text-in-image. Use this for posters, Midjourney for art. |
