TaglineAnthropic's CLI agent. Opus-powered, operates on your repo directly.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.One API, every model. Pay-as-you-go, no subscriptions.Run any open-source AI model with an API call.

PricingPart of Claude Pro/Max/Team plansWaitlist / Beta (pricing not yet disclosed)Pay per token — model-dependentPay per second of compute
Best forDevelopers who want an agent, not autocomplete. Large refactors, tests, docs.iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.Developers experimenting across models. Apps that want fallback logic.Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths
  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • 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
  • 300+ models from one endpoint
  • Automatic fallbacks between providers
  • No subscription — just pay what you use
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
Weaknesses
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • 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
  • Slight markup over direct API
  • Some provider features not exposed
  • Cold starts on less-popular models
  • Pricing gets real at scale
Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.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 model-shopping. I use this for every prototype before committing.S-tier for open-source model APIs. The default in this space.
