  • Still pre-launch / beta — zero proven track record and no public pricing yet
  • 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 vs Claude/ChatGPT
  • Less flexible than raw chatbot
  • Pricey for serious volume
  • Long shots still feel off
  • Ethics — easy to misuse
Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.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.)B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
