| Kai's verdict | A-tier in its niche. The only one that actually gets emotion right. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Niche but beloved. If you've outgrown Notion, try this. |
