Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
