| Kai's verdict | A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
