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
  • Stricter content policy than competitors
  • Hit-or-miss on complex motion
  • Text-in-video still struggles
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
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.)A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
