How do founders turn ideas into clickable prototypes in hours (v0, Figma AI, Lovable)?

Pick one prompt-to-app tool and write a paragraph describing the user, the screen, and the action: v0 gives you polished web UI, Lovable gives you a full app with auth and a database, and Figma Make turns designs or prompts into working prototypes inside Figma. All three produce a shareable URL the same day. The craft is iterating in small steps, one screen or feature per prompt, then sharing the link and refining from real reactions instead of polishing in private.

A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
