Kai's verdictS-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.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
