Kai's verdictA-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.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
