Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
