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.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
