Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.
