| Kai's verdict | S-tier. Category leader. Nothing else is close yet. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. |
