PromptVault Pro — Interactive Preview

When I launch a product, I always run into the same problem:

Screenshots look nice, but they don't show what it's actually like to use the app.

So I tried something different.

Instead of publishing images or a video demo, I created a real interactive preview. People can open the app, explore the interface, use the core features, and experience the design before deciding if the full version is worth it.

I'm curious what other founders think.

Would you rather try an interactive preview than scroll through screenshots?

I'd love your honest feedback on the idea.
