| Tagline | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | OpenAI's video model. Long clips, cinematic quality. | 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. | Voice AI that reads + expresses emotion. |
| Category | Coding | Video | Agents | Voice |
| Pricing | Part of Claude Pro/Max/Team plans | Included with ChatGPT Plus/Pro | Waitlist / Beta (pricing not yet disclosed) | Free tier + pay-as-you-go |
| Best for | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | ChatGPT subscribers experimenting with cinematic shots. | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Therapy apps, customer service, any voice agent where emotion matters. |

| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | 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 in its niche. The only one that actually gets emotion right. |
