What Is a Deepfake?

A deepfake is a fake video or audio clip where an AI puts one person's face or voice on top of something they never did or said. The word comes from deep learning and fake.

Some deepfakes are funny, like a silly video of a celebrity dancing to a new song. Some are mean and used to embarrass or trick people. Some are scary and used to scam or bully someone.

Why deepfakes hurt, even if they are fake

A mean deepfake of you can feel just as awful as a real mean picture of you. Maybe worse, because you never did the thing. Once it is out there, it is hard to delete. It can stick with the person for years.

People might believe the fake is real
The target might be too scared to go to school
The target's family sees it too
Even if everyone knows it is fake, the feeling is still bad

What to do if you see a deepfake of someone

Do not share it. Not even to make fun of it. Every share spreads the harm.
Do not comment on it. Comments push it higher in the feed.
Screenshot it as evidence, then report it to the app or site.
Tell a grown-up you trust. A parent, a teacher, or a school counselor.
If it is a friend or classmate, reach out to them privately. They probably feel terrible.

The law is catching up

In 2024 and 2025, countries around the world passed new laws against deepfake harassment. In the US, the Take It Down Act was signed in 2025, which requires websites to remove harmful deepfakes within 48 hours. Other places have similar rules now.

It is easier to make a deepfake than to clean one up. That is why we care so much about stopping them before they start.
— A researcher who studies online harm

The big idea: deepfakes can hurt real people. Do not make them, do not share them, and if you see one, report it. Being kind online is one of the most powerful things you can do.
