Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. S-tier if you self-host. The reason open-source image gen matters.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
