Kai's verdictB-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.S-tier. Market leader with reason. Start here for serious video.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
