Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
