Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Solid product but crowded market. Try it if Notion AI feels too 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.
