Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
