  • Very photoreal
  • Best open-weight model
  • Sources every claim

  • Spaces for persistent context
  • Up to 20-sec clips at 1080p

  • Storyboard feature for longer narratives
  • Remix existing videos
Weaknesses
  • 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
  • Harder to use than hosted tools
  • Needs infra
  • Not a general chatbot
  • Answers can be shallow on complex topics
  • Stricter content policy than competitors
  • Hit-or-miss on complex motion
  • Text-in-video still struggles
Kai's verdictThe 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.)A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
