Kai's verdict	S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
