Kai's verdictA-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier inside Photoshop (Generative Fill). B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
