Questions

How much does the quick app demo template cost to make?

Each one costs about $0.20 in AI credits, paid at cost with your own key. OpenPromo adds no markup. Writing the script is a few cents, and you see it before anything is made.

Rendering again after an edit only pays for the scenes you changed.

Do I have to write the script?

No. Add your website and OpenPromo reads it: what you sell, your prices, your reviews, your colours and fonts. The writer fills the template from that, and you can edit every scene, or give it an angle such as a product or an offer.

Which AI models make it?

ElevenLabs v4, Lyria 3. They were picked in a side-by-side test of the image, video and voice models available, on quality for the price.
