Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
