| Kai's verdict | 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.) | S-tier for builders. The right primitives. What Kai is built on under the hood. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for data teams. S-tier if you already live in SQL + Python. |
