Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
