Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
