| Kai's verdict | A-tier. Niche but beloved. If you've outgrown Notion, try this. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. |
