| 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. | The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.) |
