| Kai's verdict | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Niche but beloved. If you've outgrown Notion, try this. | A-tier for creators training custom looks. B-tier for general use. |
