Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-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 price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
