If you've got Photoshop or GIMP, you can get a similar effect with the "threshold" feature.
It’s essentially that! It requires a guassian blur, threshold and an overlay image of some kind. I’ve made a Photoshop plugin that automates the same process: https://chaoclypse.itch.io/noise-dystopia-machine
This web tool is primarily for those who don’t have Photoshop or don’t want to use it!
