Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.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.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
