Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
