Is there a SaaS platform can generate the launch page with key input effects?

Hi, All,
While browser the following website: https://www.boardofinnovation.com/
The key input effect is very interesting. We are preparing our product launch page, so is there a SaaS service that can generate something like that? There is another website https://continual.ai/ with a similar effect. And it has an animation graph that shows how it works, is there any SaaS platform can generate it?
