| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | 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.) | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. |
