Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier. Category leader. Nothing else is close yet.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
