DeepNude was a standalone application that utilized neural networks—specifically a technology called Generative Adversarial Networks (GANs)—to manipulate images of clothed women, making them appear nude. The software was essentially an automated "x-ray" tool, but rather than manipulating light, it was inventing new imagery based on patterns it learned from thousands of nude photographs.

: Use of these tools without explicit consent from the subject is widely considered unethical and may be illegal under deepfake and privacy laws in various jurisdictions.

Despite the official shutdown of DeepNude v2.0.0 Premium, the damage was done. The software had been pirated and shared across the internet. The source code (or variations of it) leaked, leading to the creation of similar open-source projects and Telegram bots that offered the same functionality for free.
