| Kai's verdict | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
