  • iPhone-only by design, which immediately locks out half the smartphone market
  • Battery drain and privacy concerns from constant ambient context scanning are real and unresolved
  • Overwhelming for beginners
  • Hosted inference pricing varies
  • Smaller community
  • Model selection more limited
Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.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 infrastructure. The one platform every AI dev eventually uses.A-tier. Close second to Cursor. If $5/mo matters, start here.
