|---|---|---|---|---|
| Tagline | 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. | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out. | Anthropic's flagship — best reasoning + longest useful context. |
| Category | Agents | Coding | Agents | Chatbots |
| Pricing | Waitlist / Beta (pricing not yet disclosed) | Part of Claude Pro/Max/Team plans | Free (open-source) | Free + $20/mo Pro + team/enterprise |
| Best for | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | 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. | Long writing, code, careful thinking, documents over 50 pages. |

| Kai's verdict | 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 if you live in the terminal. Different shape than Cursor — complementary, not replacement. | 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.) | S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work. |
