What tool/service can create conversion flow like this?

Recently, I signed up for some online courses, and I realized that they always put me through a conversion flow with many questions and very persuasive tactics to ensure I use the service.

Here are some images of the questions

It's look simple, just question and answer with image, sometime it's single choice and sometime is multiple choice.

And it's show the analytic page based on your answer.

Almost the course have the same layout so I think there will be a tools or SAAS for this.

Does anyone know which tools can be used to create such a high-converting landing page?

Thank you everyone!

does anyone know this?
