| Kai's verdict | S-tier infrastructure. The one platform every AI dev eventually uses. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
