“Nudify” apps are AI tools that take an ordinary, clothed photo of a real person and generate a fake nude image from it. They have spread fast, they overwhelmingly target women and girls, and — the part every parent needs to understand — they are increasingly being used by teenagers against their own classmates. If you’ve heard the term and want to know what it means, how worried to be, and what to do if your child is affected, this guide covers it. It contains no instructions and names no apps; its purpose is to help you protect your child.

The most important thing to hold onto before anything else: if your child is ever targeted by a fake image, it is not their fault, they are not in trouble, and shame is exactly what keeps these images spreading. A child who knows they can come to you without being blamed is a child you can actually help.

What Are Nudify Apps?

A nudify app uses generative AI to alter a photo so that a clothed person appears nude. The source image is usually completely ordinary — a photo pulled from a social media profile, a school website, or a group chat. The resulting image is fake, but it can look convincingly real, and that is what makes it so damaging: the harm to the person targeted is genuine even though the image is not.

These tools are disturbingly easy to reach. Investigations have found them advertised openly and even surfaced through mainstream app stores and sign-in systems, which lends them a false air of legitimacy. The barrier to using one is low, and that is a large part of the problem.

How Big Is the Problem?

Larger than most parents realise, and growing. An investigation by Wired documented victims across more than 90 schools in at least 28 countries — and those were only the cases that reached the news. One researcher estimated that as many as 1.2 million children may have been targeted by sexual deepfakes in a single year.

Two patterns matter for parents. First, this is overwhelmingly gendered: an estimated 99% of nude deepfakes depict women and girls, and many nudify tools don’t even function on photos of boys. Second, in the school cases that have come to light, it is typically teenage boys creating fake images of their female classmates — which means this is not only a “stranger danger” issue but, often, something happening between children who know each other.

It’s Illegal — and That Matters for Every Parent

The law has moved quickly, and it cuts two ways: it protects victims, and it means a child who creates these images can be committing a serious crime.

In the United States, the federal Take It Down Act, signed in May 2025, makes it a crime to knowingly publish or threaten to publish non-consensual intimate images — explicitly including AI-generated “digital forgeries.” As of May 2026, covered platforms are required to remove such content within 48 hours of a valid request. Separately, and importantly, a sexually explicit fake of a minor can already be prosecuted under existing child sexual abuse material laws — which means a teenager who makes one of these images of a classmate may be committing a federal offence, not playing a prank. Other countries have introduced similar or stronger laws.

This is a conversation to have with your child from both directions: that they are protected if someone targets them, and that creating or sharing such an image of someone else — even “as a joke” — can carry life-altering legal consequences. Many teenagers genuinely do not understand that the fake image of a classmate they were shown, or forwarded, is treated in law as child sexual abuse material.

What to Do If Your Child Is Targeted

If a fake image of your child exists or is being used to threaten them, act calmly and in this order:

  1. Reassure them first. Before anything technical, tell your child plainly that this is not their fault, they are not in trouble, and you will help them. Shame and fear are what keep victims silent and images circulating.
  2. Don’t pay or respond to threats. If someone is using an image to blackmail your child (sextortion), paying rarely stops it and usually invites more. Stop engaging.
  3. Preserve evidence without forwarding it. Note URLs, usernames, dates and the platform. Do not download, forward or share the image itself — of a minor, that can itself be an offence.
  4. Use the removal tools. NCMEC’s free Take It Down service helps get intimate images of minors removed from participating platforms, and covered US services must act on valid requests within 48 hours. Report the content through the platform’s own process too.
  5. Report it. Contact NCMEC’s CyberTipline, or the police. In the UK, the Internet Watch Foundation and Report Remove (via Childline) can help.
  6. Tell the school if classmates are involved. Most incidents that surface are between students, and the school needs to know to act and to protect your child.

How to Protect Your Child Before It Happens

Prevention here is less about blocking a specific app — new ones appear constantly — and more about awareness and relationship.

Have the conversation early

Talk to your child about deepfakes and nudify tools before they encounter them. Explain what they are, that the images are fake but the harm is real, that creating or sharing one is illegal, and — most of all — that if they’re ever targeted, or shown an image of someone else, they should come to you and won’t be in trouble for telling you.

Tighten what’s public

Because these tools work from ordinary photos, a more private social media footprint reduces the raw material. Setting your child’s accounts to private, and being thoughtful about how many clear face photos are publicly visible, lowers the risk — though it can’t eliminate it, since school and group photos exist too.

Make sure they understand the “bystander” side

A child is far more likely to be shown one of these images than to be the direct target. Teaching them not to forward it, to tell a trusted adult, and to support rather than pile on the person targeted turns them from part of the spread into part of the solution.

Where Monitoring Fits

This is primarily a matter of law, schools and conversation rather than software — no monitoring app blocks the underlying problem. Where visibility can help is in a parent noticing distress or a change in behaviour early, and in being aware of the apps and contacts in a child’s digital life so a problem can be raised before it grows. As everywhere on this site, any such tool works best used openly, with your child’s knowledge, as a support for the conversation above rather than a substitute for it. If you’re weighing options, our parental control comparison lays them out. But on this issue specifically, the strongest protection is a child who will tell you when something is wrong.

If Your Child Has Been Affected

Being targeted by a fake intimate image is genuinely traumatic, and the distress is real regardless of the image being fake. Reassure your child it isn’t their fault, take the reporting steps above, and get them support. In the US, the 988 Suicide and Crisis Lifeline is available by call or text, and the Crisis Text Line responds to HOME texted to 741741; in the UK, Childline is 0800 1111 and its Report Remove tool can help take images down. findahelpline.com lists services by country. If your child is in immediate danger, contact emergency services.

Frequently Asked Questions

What are nudify apps?

Nudify apps are AI tools that take a clothed photo of a real person and generate a fake nude image from it. The source photo is usually ordinary — from social media or a school page — and while the image produced is fake, it can look real, and the harm to the person targeted is genuine. They overwhelmingly target women and girls and are increasingly used by teenagers against classmates.

Are nudify apps illegal?

Creating or sharing sexually explicit fake images is increasingly criminal. In the US, the federal Take It Down Act criminalises knowingly publishing non-consensual intimate images including AI deepfakes, and a sexual fake of a minor can be prosecuted under existing child sexual abuse material laws. That means a teenager who makes such an image of a classmate — even as a “joke” — can be committing a serious crime. Many other countries have passed similar laws.

What do I do if someone made a fake nude of my child?

Reassure your child it’s not their fault and they’re not in trouble. Don’t pay if there’s a threat. Preserve evidence (URLs, usernames, dates) without forwarding the image. Use NCMEC’s free Take It Down tool to seek removal, report to the platform and to NCMEC’s CyberTipline or police, and tell the school if classmates are involved. Under the Take It Down Act, covered platforms must remove valid reports within 48 hours.

How can I protect my child from nudify apps?

Talk to them early about what these tools are, that the images are fake but the harm is real, and that both being targeted and creating an image of someone else are serious matters they should bring to you. Set social accounts to private to reduce the public photos these tools rely on, and teach them not to forward such an image if they’re shown one, but to tell a trusted adult. The strongest protection is a child who feels safe telling you when something goes wrong.

My child created or shared one of these images — what should I do?

Take it seriously; this can be a criminal matter, not just a discipline issue. Address it directly with your child, make clear why it’s harmful and illegal, preserve any evidence, and cooperate with the school and, where appropriate, authorities. It’s also worth understanding that some children who do this don’t grasp the severity — which is why the preventive conversation about consequences, before anything happens, matters so much.
