Kai's verdictB-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.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
