It definitely works to some extent—the nudify guesses what might be under the clothes based on training data, but it’s not like it reveals the “real” person. It's all generated content, not an actual uncovering. Still, it’s controversial because even though it's synthetic, it can be used to harass or humiliate people, especially if misused. I wouldn’t recommend trying it on pictures of people you know or sharing anything generated—could lead to legal trouble or get your accounts banned on social platforms.
