Strengths
  • Sources every claim
  • Fast, current answers
  • Pro Search runs multi-step research
  • Spaces for persistent context
  • 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
  • Strong pre-launch signal: 25k+ waitlist and backing from a16z, True Ventures, and SV Angel
  • Real songs with real lyrics
  • v4 is very good
  • Quick turnaround
  • Edit audio/video by deleting text
  • Overdub (voice clone) for fixes
  • Strong collaboration + remote recording
Weaknesses
  • Not a general chatbot
  • Answers can be shallow on complex topics
  • 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
  • Copyright gray zone
  • Audio quality behind studio
  • Not a traditional NLE — some workflows awkward
  • Overdub ethics require care
Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.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 in its category. The first AI music tool I'd actually listen to.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
