| Kai's verdict | A-tier. Niche but beloved. If you've outgrown Notion, try this. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
