Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier for designers. The only one that takes vectors seriously.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
