|---|---|---|---|---|
| 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. | Chat with your data. Upload a CSV, ask questions, get charts. | OpenAI's browser agent. Clicks and types on websites for you. | Cognition Labs' autonomous coding engineer. |
| Category | Agents | Data | Agents | Agents |
| Pricing | Waitlist / Beta (pricing not yet disclosed) | Free + $20-$65/mo | Included with ChatGPT Pro $200/mo | $500/mo |
| Best for | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Analysts, founders, anyone with a spreadsheet + a question. | Power users willing to pay $200/mo for a browser bot. | Engineering teams offloading tickets. Ops/platform work. |

| 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 for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | B-tier. Still early. Manus is more flexible for less money. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. |
