  • Battery drain and privacy concerns from constant ambient context scanning are real and unresolved
  • Academic-only
  • Can hallucinate citations — verify everything
Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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 academic research. Nothing else comes close for systematic reviews.
