Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Bet on this one — the Sparkpage format is genuinely new.
