| Kai's verdict | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. | S-tier for solo + free. The best free option, hands down. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. |
