  • 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
  • Pricey for serious volume
  • Long shots still feel off
  • Ethics — easy to misuse
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.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 multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
