| 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. | Google's answer. Best integrated with Workspace + free for a lot. | AI search done right. Cited answers, not chat theater. | Chat with your data. Upload a CSV, ask questions, get charts. |
| Category | Agents | Chatbots | Research | Data |

| Best for | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Anyone already on Google, research tasks, summarizing long documents. | Replacing Google for any question where you want a cited answer in seconds. | Analysts, founders, anyone with a spreadsheet + a question. |

| 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.) | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. |
