How do AI deepfakes trick people into believing fake content?

AI deepfakes trick people by making fake videos look just like real ones, so you can't tell them apart.

Imagine your favorite cartoon character comes to life and talks to you, that's kind of what AI deepfakes do. They take a real person’s face or voice and change it to make it seem like someone else is speaking or acting.

AI deepfakes use special computer tools that learn from lots of videos. These tools study how people move their mouths, eyes, and faces when they talk. Then, the AI uses this knowledge to copy those movements onto a different face, making it look like someone else is saying something they didn’t say.

It’s like when you draw a picture on a piece of paper, then use a mirror to make it look like your friend is drawing it. The trick works because your brain sees the same patterns and thinks everything is real.

Sometimes AI deepfakes can even change what someone says, like turning "I love ice cream" into "I hate broccoli." Your brain might not notice if the person's face looks just right!
