TaglineAn 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.VS Code fork that made AI coding actually work.Anthropic's CLI agent. Opus-powered, operates on your repo directly.Suno's main rival. Often better on instrumental nuance.

Best foriPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.Developers. Non-developers who want to ship working code.Developers who want an agent, not autocomplete. Large refactors, tests, docs.Musicians comparing AI outputs. Anyone who didn't click with Suno.
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
  • Tab completion feels like mind-reading
  • Composer for multi-file edits
  • Runs Claude, GPT, Gemini — you pick
  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • Strong instrumentals + genre fidelity
  • Extend/remix features
  • Good lyric understanding
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
  • Can feel overwhelming for non-coders
  • Expensive at scale
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • Same copyright gray zone as Suno
  • Ecosystem smaller
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 coding. If you write code of any kind, this pays back the $20 in a day.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
