|---|---|---|---|
| Tagline | The GitHub of AI. Models, datasets, spaces — all in one. | 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 | Dev Platform | Agents | Agents |
| Pricing | Free + $9-$20/mo + enterprise | Waitlist / Beta (pricing not yet disclosed) | Free tier + $39-$199/mo |
| Best for | Any ML/AI developer. Hobbyists exploring open models. | 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 | S-tier infrastructure. The one platform every AI dev eventually uses. | 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. |
