Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
