Kai's verdictS-tier for teachers. If you teach K-12, start here this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
