Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
