| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | 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 for individuals — Claude does this for less. A-tier for teams needing brand consistency. |
