FWIW I think it could get a pretty high fidelity mockup if I had spent more time with it! It was remarkably good for a single one-shot prompt which probably had 15 words or less. I'll definitely come back for more when the time is right.
Definitely — we've seen some pretty crazy high fidelity mock ups from our customers who spend hours and hours prompting away, and they genuinely blow my mind. it's honestly why we spend so much time working on the application layer (e.g. making it easier to feed context into your prompt, referencing other designs, etc) since we know that the LLM is capable of these things, it just takes much more time than most people are willing to put in.
would love to hear what you think when you give it another try!
