Kai's verdictS-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier in its category. The first AI music tool I'd actually listen to.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.
