Can you vibecode this?

Yes

The core loop — LLM turns a text prompt into a mobile app — is pure code. The design tool and chat-based builder both wire up to commodity AI APIs. A solo founder already ships and runs this at 90%+ margins with no employees. Nothing here requires a licence, catalogue, or headcount.
