| Kai's verdict | S-tier for solo + free. The best free option, hands down. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | 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. |
