Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
