ShindanMaker is a popular Japanese website that allows users to create simple, text-based 'diagnosis' games based on input names. Launched in 2010, it became a global sensation on platforms like Twitter/X, especially within the anime and VTuber fandoms. The memes typically feature nonsensical or oddly specific results—such as 'What kind of bread are you?' or 'Your fortune for today'—often leading to hilarious and unexpected outcomes. On memeOS, you can replicate this iconic format to mock trends, roast friends, or create custom personality tests that look exactly like the viral screenshots shared across social media.
