Kai's verdictS-tier for open-source model APIs. The default in this space.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 most interesting spreadsheet in years. Great for ops dashboards.
