Where did that program go where you could "de-edit" a photo?

Sorry for the odd title, I didn't know what to put. Anyways here is the better worded, longer question.Awhile ago someone on here wrote a program where you could upload an image and the program would break down the editing style and show you what all was applied to the image. It would bring up the settings that was used via Lightroom or what not. Anyone know what i'm talking about? via /r/photography http://ift.tt/2hNknmq
