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.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.OpenAI's image model. Built into ChatGPT Plus.OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out.

PricingWaitlist / Beta (pricing not yet disclosed)Token-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens.Included with ChatGPT Plus $20/moFree (open-source)
Best foriPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch.ChatGPT Plus users who want images without paying extra.Engineering teams already using Linear + OpenAI Codex who want to stop babysitting agent sessions and instead let the issue tracker drive autonomous coding at scale.
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
  • Same runtime as the Cursor IDE — no reinventing sandboxing, context management, or model routing
  • Three execution modes: local machine, Cursor cloud VMs (isolated per-agent), or self-hosted workers for air-gapped teams
  • Cloud agents are durable — keep running even if your laptop sleeps or connection drops, and can open PRs automatically on finish
  • Full harness included: codebase indexing, MCP servers, skills, hooks, and multi-agent delegation via subagents
  • Visible in Cursor's Agents Window — programmatic runs can be inspected or taken over manually in the IDE
  • Excellent prompt understanding
  • Built into ChatGPT — no extra subscription
  • Good at composition + concepts
  • Fully autonomous ticket-to-PR pipeline: every open Linear issue gets its own isolated Codex agent without manual supervision
  • Fault-tolerant Elixir/OTP architecture automatically restarts crashed agents and manages hundreds of concurrent runs
  • WORKFLOW.md keeps all orchestration policy version-controlled inside the repo, so agent behavior is reproducible and reviewable like code
  • Proven internal results: OpenAI reported a 500% increase in landed PRs on some teams within three weeks
  • Open spec encourages community re-implementations in any language, not just Elixir
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
  • TypeScript-only SDK — no official Python or other language bindings at launch
  • Public beta status means API surface and pricing can shift without much notice (Cursor has a track record of surprise pricing changes)
  • Cloud VM costs layer on top of subscription credits, making cost estimation non-trivial at scale
  • Aesthetic ceiling below Midjourney + Ideogram
  • Text rendering worse than Ideogram
  • No fine control
  • Currently only supports Linear as an issue tracker — GitHub Issues and Jira integrations are not yet official
  • Only OpenAI Codex is officially supported as the agent runtime; other model integrations are community-contributed and incomplete
  • Self-hosted, Elixir-dependent engineering preview with no built-in sandboxing — not suitable for untrusted or production environments out of the box
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.)If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.)B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.Symphony is the most architecturally serious 'issue tracker as control plane' approach yet — 15K GitHub stars in weeks confirms the idea resonates — but it's still a rough, self-hosted engineering preview that demands Elixir chops and a Linear-only workflow. (Verdict pending Phi's full review.)
