Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.
