Show HN: Souschef – AI demo video from a prompt(v0 + Screen Studio + ElevenLabs)

Hi HN, I’m building Souschef, an AI tool that creates realistic product demo videos from just a written prompt—no UI, design tools, or code required. The idea came from a common problem we faced as founders: it's hard to pitch or test a product idea before it's built. Most tools assume you already have a UI or prototype. We wanted to go one step earlier — when you just have an idea. With a single prompt, Souschef can: Generate realistic UI screens Animate user flows and transitions Add voiceover narration Export a polished, ready-to-share demo video Use cases include: Validating early product ideas Running go-to-market experiments Exploring product ideas before committing design/dev resources We’re opening a closed beta for 100 testers in May, and gradually expanding access. If this sounds useful, join the waitlist here: https://souschef.framer.website https://souschef.framer.website We’re building in public and would love your thoughts or feedback. Thanks for reading!
