| Tagline | Spreadsheets with AI + live integrations baked in. | 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. | OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out. | Build a full app from a prompt. Stripe-ready. |

| Best for | Ops teams, marketers, anyone building dashboards from multiple sources. | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | 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. | Non-devs + solopreneurs shipping MVPs. |

| Kai's verdict | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | 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.) | 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.) | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. |
