Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
