Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier for creators training custom looks. B-tier for general use.
