Before-After Comparison Tool

26 days ago from , Designer

Guys, I'm looking for an online tool that I can use to show the differences between two designs, a comparison tool if you want.

Here's an example of something that does this: http://preview.codecanyon.net/item/slim-beforeafter-image-comparison-slider/full_screen_preview/24286873?_ga=2.209502289.2124551458.1592397429-1405243823.1592397413

I want to be able to upload the old and the new designs and show (with the help of a tool like this) the differences between the two designs in an easy way without having to explicitly mention every change that was made on the newer design. I'm not sure if something like this exists but maybe it does and I was not able to find it.
