| 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 price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up. |
