| Kai's verdict | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes. |
