Kai's verdictS-tier for designers. The only one that takes vectors seriously.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
