|---|---|---|---|
| Tagline | Cognition Labs' autonomous coding engineer. | 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. | Autonomous AI agent that actually finishes tasks. |
| Category | Agents | Agents | Agents |
| Pricing | $500/mo | Waitlist / Beta (pricing not yet disclosed) | Free tier + $39-$199/mo |
| Best for | Engineering teams offloading tickets. Ops/platform work. | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | People who want to hand off tasks entirely — trip planning, research, spreadsheet building. |

| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | 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 in the agent category. The first one I'd give to a non-technical friend. |
