TaglineTerminal-based AI pair programmer. Git-aware, model-flexible.Prompt to UI design. Figma-ready outputs.An agentic iPhone home screen that replaces your static icon grid with AI widgets that proactively surface health, calendar, finance, and local context — without you having to open a single app.
CategoryCodingDesignAgents
PricingFree (open source) + whatever API you useFree trial + paid plansWaitlist / Beta (pricing not yet disclosed)
Best forDevelopers who want open-source tooling with full control.Designers brainstorming first drafts.iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.
Strengths
  • Works in any terminal
  • Auto-commits changes with meaningful messages
  • Works with any model (Claude, GPT, local)
  • Minimal learning curve
  • Prompt-to-UI with real layouts
  • Exports to Figma
  • Faster than hand-designing from scratch
  • 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
Weaknesses
  • Terminal-only
  • Less agentic than Claude Code
  • Setup on Windows is fiddly
  • Output needs designer polish
  • Pricing unclear / changes often
  • 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
Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Useful for first drafts. v0 is the better bet for shipping code.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.)
