| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | 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. |
