  • Battery drain and privacy concerns from constant ambient context scanning are real and unresolved
  • Pricey for casual use
  • Fiction-only focus — not for business writing
Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.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 fiction. If you're writing a novel, this beats raw ChatGPT every time.
