Long clips, cinematic quality. | Prompt to full song with vocals, instruments, the works. | 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. |

| Best for | ChatGPT subscribers experimenting with cinematic shots. | Jingles, intros, demos, sketches, personal use. | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. |

| Kai's verdict | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier in its category. The first AI music tool I'd actually listen to. | 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.) |
