| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | 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. |
