|---|---|---|---|---|
| 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. | A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number. | Run any open-source AI model with an API call. | AI avatar videos. Record once, speak any language. |
| Category | Agents | Agents | Dev Platform | Video |
| Pricing | Waitlist / Beta (pricing not yet disclosed) | Free for consumers; standard Stripe per-transaction fees for merchants | Pay per second of compute | Free + $24-$65/mo |
| Best for | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data. | Developers using open-source models (Flux, SDXL, Whisper, etc). | Course creators, multilingual marketers, anyone scaling video content. |

| 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.) | Stripe Link is the most credible first move toward a real agentic payment layer — the one-time-use card model is genuinely clever, and the existing merchant network gives it a head start no startup wallet can match. But the 'approve every transaction' UX will get old fast, and the hard part (autonomous spending with guardrails) is still on the roadmap. (Verdict pending Phi's full review.) | S-tier for open-source model APIs. The default in this space. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. |
