PricingWaitlist / Beta (pricing not yet disclosed)Free tier + pay-as-you-goFree + $28+/user/mo
Best foriPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.Therapy apps, customer service, any voice agent where emotion matters.Data teams at startups + enterprises.
Strengths
  • 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
  • Detects + mirrors emotional tone
  • EVI (Empathic Voice Interface) feels different
  • Expressive voice output
  • SQL + Python + no-code in one notebook
  • Magic AI writes queries + viz for you
  • Team-grade collaboration
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
  • Niche use case
  • Pricing ramps fast
  • Overkill for casual users
  • Enterprise pricing
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 in its niche. The only one that actually gets emotion right.A-tier for data teams. S-tier if you already live in SQL + Python.
