Existential Check is Ridiculous Software's answer to challenges of generative AI. The world is now flooded with images that may have been generated by computers. Many pictures of people you see are actually of people who do not exist. This can create an existential doubt: do I exist? Is this selfie I've just taken a picture of a person who exists? Existential Check will solve those problems! Using a Machine Learning model trained on pictures of people who do not exist, this app lets you take a selfie and check whether you exist or not.
