Is there a Skeleton UI Design Generator?

Question

User interface

Hello.
Attention! Please note that this is not an advertisement!
Please get to the bottom of the issue.

Background:
Usually in website development projects, sketches are first drawn and agreed with customers. And at this stage there are no problems at all, I know at least 4 cool resources for drawing sketches and prototypes:
https://wireframe.cc
https://presentator.io
https://moqups.com
https://mockingbot.com
not counting Sketch, Adobe XD and inVision Studio. But that's not the point. Let's say it so happened that the product has already been made for a long time, without sketches and prototypes, it works without bugs and freezes, and it needs to be launched not just in production, but as a presentation for advertising. Here the most interesting begins. It would seem that take a screenshot of the product, paste it into an action or mockup, and that's it, look, here is our product, it looks like this! And that's how it works! BUT! And if, for reasons of the user agreement and privacy policy, I cannot or do not want to show the client's photo, text or name. Skeleton Design can come to the rescue to hide all personal and private data. Visually, everything is the same, both color and size, and it looks cool.

Ummm... but to make it so beautiful, you have to manually cover up the text and pictures???
I came across different solutions for website design. You can choose the font and color, and generate waves on svg that are worn to the ears to make unusual transitions between blocks, and choose the right gradient, for example:

That is, you don't have to worry, everything is already online. And how to generate Skeleton UI Design from a screenshot?
So that I can upload an image, and get something like this:

This is especially true as a guide for beginners. Show how to do it. The latter will most likely have to be done in Adobe After Effects or similar programs with animation.
I decided to search the Internet for a solution for generating images in skeleton design. Guess what the search engines came up with? I have never seen so many skeletons in my life. Well, human...

It was a cry from the heart, is it really not clear what I'm looking for. And I despaired until I remembered Habr and his "Toaster". By the way, for those who don’t understand, I know how to do skeleton design , so I don’t need to send links to scripts that do such a download:

If the situation is clear, then I have a

QUESTION:
Are there such services, scripts, sites or programs that convert ready-made design with private elements in a schematic colored skeleton UI design?
It is clear that the animation for the presentation will most likely have to be done by yourself.
The only question is the ability to create a schematic overall picture of the product.
Maybe someone knows? Tips, recommendations, suggestions?

Thank you all in advance
