Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for text-in-image. Use this for posters, Midjourney for art.
