Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
