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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier in its niche. The only one that actually gets emotion right.
