Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
