| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
