| Kai's verdict | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for ops automation. B-tier for simple copy (use Claude). | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
