Weaknesses
  • Expensive for just notes
  • Smaller community than Obsidian
  • Less agentic than Cursor/Claude Code
  • Model quality varies
  • 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
  • Pricing gets steep for production use
  • Some voices sound over-polished
Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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. Category leader. Nothing else is close yet.
