Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for local inference. If you care about privacy or want to tinker, install this today.
