Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier for model-shopping. I use this for every prototype before committing.
