Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Still early. Manus is more flexible for less money.
