Newsround has been investigating what a deepfake is, and what they are used for.
Deepfakes are videos, picture or audio clips made with artificial intelligence to look real.
They can be used for fun, or even for scientific research, but sometimes they're used to impersonate people like politicians or world leaders, in order to deliberately mislead people.
