Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
