Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
