Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
