Best foriPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.Long writing, code, careful thinking, documents over 50 pages.Developers who want open-source tooling with full control.Teams with GitHub already. Devs who don't want to change IDEs.
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
  • Best-in-class writing + nuanced reasoning
  • 1M context on Opus
  • Artifacts for code/docs
  • Lowest hallucination rate in my testing
  • Works in any terminal
  • Auto-commits changes with meaningful messages
  • Works with any model (Claude, GPT, local)
  • Minimal learning curve
  • Great enterprise story
  • Works in your existing IDE
  • Chat + autocomplete
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
  • Image generation is weak
  • No native web search on all tiers
  • Terminal-only
  • Less agentic than Claude Code
  • Setup on Windows is fiddly
  • Less agentic than Cursor/Claude Code
  • Model quality varies
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.)S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
