Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for solo + free. The best free option, hands down.	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.
