Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
