Strengths
  • Tab completion feels like mind-reading
  • Composer for multi-file edits
  • Runs Claude, GPT, Gemini — you pick
  • Strong templates
  • Decks, docs, webpages
  • Doesn't look generic
  • Ambient, proactive intelligence delivered via native iOS widgets — no app-switching required
  • Cross-domain context: health, calendar, email, finances, and local recommendations in one layer
  • Works within iOS permission model (no jailbreak or sideloading), making App Store approval plausible

  • Built into ChatGPT
  • Good for repetitive web tasks
Weaknesses
  • Can feel overwhelming for non-coders
  • Expensive at scale
  • Locked into Gamma's format
  • Export quality varies
  • 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
  • Slow vs doing it yourself
  • Breaks on complex auth flows
  • $200/mo gate
Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.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. Still early. Manus is more flexible for less money.
