Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
