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

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

We’re building in public and would love your thoughts or feedback. Thanks for reading!
