Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for academic research. Nothing else comes close for systematic reviews.
