| Kai's verdict | A-tier. Niche but beloved. If you've outgrown Notion, try this. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | S-tier for open-source model APIs. The default in this space. |
