Generate the prototype
Copy a ready-made prompt into any AI, or generate a clickable prototype live.
Copy prompt no key
Builds a tailored prompt. Paste it — with your images attached — into Claude, ChatGPT, v0 or Lovable. Safe to hand to every participant.
Generate live your key
The tool calls the AI itself and renders a clickable prototype right here. Needs your own API key, used only in your browser.
Don't forget the images. This prompt describes the idea — attach your 0 sketch(es) to the same message so the AI can see them. In Claude/ChatGPT use the paperclip; in v0/Lovable drag the images in.
Working…
Your key is sent directly from your browser to the provider to make this one request — it is never stored and never touches any Peter Spiegel server. For a shared workshop, use “Copy prompt” instead.
