| Kai's verdict | A-tier for creators training custom looks. B-tier for general use. | A-tier in its niche. The only one that actually gets emotion right. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. |
