Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
