Strengths
  • AI auto-links related notes

  • 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
  • Edit audio/video by deleting text
  • Overdub (voice clone) for fixes
  • Strong collaboration + remote recording
  • Pull live data from Stripe, Slack, Google Analytics, etc.
  • AI functions inside cells

Weaknesses
  • Expensive for just notes
  • Smaller community than Obsidian
  • 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
  • Not a traditional NLE — some workflows awkward
  • Overdub ethics require care
  • Not a full Excel replacement for heavy users
  • Integrations best on paid tiers
Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.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 for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
