Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Still early. Manus is more flexible for less money.
