What Counts as AI Porn?
AI porn, broadly, is any explicit visual content produced or substantially altered by generative machine learning rather than captured on camera in the traditional sense. That spans a wide range: fully synthetic images of people who don't exist, video generated frame by frame from a text prompt, and face-swapped or 'deepfaked' content built on top of real footage. The sites in this category are galleries and platforms that curate or produce this kind of material, as distinct from the generator tools themselves, which get their own category on this site. We're comparing them on how convincing the output actually looks, how frequently new content is added, and how clearly each platform handles consent and likeness issues around real people.
How the Technology Got Here
The technology underlying this category is recent and moved fast. Text-to-image diffusion models went from research curiosity to mainstream tool in 2022, when systems like Stable Diffusion and Midjourney made high-quality image generation accessible to anyone with a browser or a decent GPU, and open-source releases meant people could run and fine-tune models locally without a company's content filters in the loop. Adult use cases followed almost immediately, since the same underlying technology that can generate a landscape or a portrait can, with the right fine-tuning, generate explicit imagery just as easily. Video generation lagged behind images by a couple of years but has been closing the gap quickly.
Terminology You'll See
A few terms are worth knowing here. A 'LoRA' or 'checkpoint' is a fine-tuned add-on or full model version trained to reproduce a specific look, style, or in some cases a specific face - the building blocks people use to steer a base model toward a particular result. 'Inpainting' is editing part of an existing image by regenerating just that region, commonly used to alter a source photo. 'Deepfake' specifically describes content that maps a real person's likeness onto footage or images they weren't actually part of, which is the area drawing the most legal and ethical scrutiny across the space. 'Prompt' is simply the text description used to steer what the model produces.
Why It Took Off So Fast
This category exploded as fast as it did because the barrier to entry collapsed almost overnight - what used to require a camera, performers, and a studio now just requires a capable model and some patience with prompting. That's opened the door to endless customization, generated on demand, at a speed and volume no traditional production pipeline can match. It's also the most legally and ethically unsettled part of the industry right now, particularly around content depicting real people without consent, which is why platform policy and moderation are things we weigh heavily when reviewing sites in this space.
