| Kai's verdict | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier for text-in-image. Use this for posters, Midjourney for art. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Bet on this one — the Sparkpage format is genuinely new. |
