| Tagline | Open weights + strong photorealism. The open-source answer. | AI search done right. Cited answers, not chat theater. | 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. | Spreadsheets with AI + live integrations baked in. |

| Best for | Developers + power users who want control and privacy. | Replacing Google for any question where you want a cited answer in seconds. | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Ops teams, marketers, anyone building dashboards from multiple sources. |

| Kai's verdict | A-tier. S-tier if you self-host. The reason open-source image gen matters. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | 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.) | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
