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 search. I use it before Google now. If you're still Googling everything, try this for a week.
