Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
