Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
