If you have ever watched a video online and thought, “Wait… did that celebrity actually say that?” you may have already encountered a deepfake. Artificial intelligence has become surprisingly good at creating fake videos, voices and images that look incredibly real.
That is why more people are starting to ask the question: What are deepfakes, and how did they suddenly become so common online? From viral TikTok clips to political controversies, AI-generated media is spreading quickly across the internet.
In this guide, we will break down how this technology works, where you might encounter it, and why it is both fascinating and slightly unsettling.

Artificial intelligence can now create videos, images and even voices that look incredibly real, making it harder than ever to tell what is genuine and what is not. In this episode, we break down what deepfakes are, how they are created and why they are becoming such a major issue online.
What are deepfakes?
Deepfakes are videos, images or audio recordings created or altered using artificial intelligence, or AI video generators, so that someone appears to say or do something they never actually did. The technology analyses real footage of a person and then generates new media that imitates their appearance and voice.
Many people discover this technology after seeing a strange or funny video online and wondering whether it is real. That moment usually leads them to search “what are deepfakes” and how artificial intelligence can create such convincing results.
In simple terms, deepfakes are like extremely advanced digital impersonations. Instead of a human actor doing the impression, a computer does it using massive amounts of data.
How deepfakes are created
Deepfakes are usually created using machine learning models trained on thousands of photos, videos or audio recordings of a person. The AI studies those examples until it learns the patterns of that person’s face, voice and expressions.
Once the system understands those patterns, it can generate entirely new footage. The computer essentially predicts what that person would look or sound like in situations that never actually happened.
Some of the most common techniques used include:
- Face swapping, where one person’s face is placed onto another person’s body
- Voice cloning, where AI copies someone’s speech style
- AI video generation, where completely new footage is created
The surprising part is that these tools are becoming easier to use every year.
The first deepfakes and how the technology spread
Deepfakes first gained attention around 2017 when online communities began experimenting with AI face-swapping tools. Early versions appeared on internet forums and often involved replacing actors’ faces in popular movie scenes.
At first, the results looked a little strange. Faces were sometimes blurred or moved awkwardly, which made the videos easy to recognise as fake. However, artificial intelligence improved rapidly, and the videos soon became far more convincing.
As software became easier to access, more creators began experimenting with AI-generated media. What started as a niche internet experiment gradually spread into mainstream online culture.
Celebrity deepfakes
Celebrities are among the most common targets of AI-generated videos. Public figures have thousands of photos and video clips online, which gives artificial intelligence plenty of data to learn from.
Many viral examples involve famous actors appearing in films they were never actually part of. Other videos recreate celebrity voices in fake interviews or humorous scenarios.
Some common examples include:
- Fake advertisements where celebrities promote products
- Movie scenes where actors are digitally replaced
- AI-generated interviews or speeches
- Comedy videos imagining celebrities in absurd situations
While many of these videos are meant as entertainment, some have also been used in scams.
Social media platforms are one of the main places where deepfakes spread quickly. Short videos that surprise or entertain people tend to go viral before anyone has time to verify them.
Platforms such as TikTok, Instagram and X have seen a surge in AI-generated content. Some creators openly label their videos as artificial, while others leave viewers guessing.
Because social media algorithms reward engaging content, a dramatic video can reach millions of viewers within hours. Unfortunately, the correction explaining that a video is fake often spreads much more slowly.
Political deepfakes
Artificial intelligence has also raised concerns in the world of politics. A convincing fake video of a public figure could potentially influence how people interpret real events.
For example, a manipulated clip might show a politician appearing to say something controversial. Even if the video is quickly proven false, the original clip may already have circulated widely online.
Researchers worry that synthetic videos could play a role in future elections. Governments and technology companies are now exploring ways to detect and regulate this type of content.
Deepfake scams and fraud
Deepfakes are not always created for entertainment. Criminals have started using AI-generated voices and videos to impersonate real people and trick victims into sending money.
In some cases, scammers create fake videos of famous entrepreneurs promoting investment opportunities. Because the person appears familiar and trustworthy, viewers may not question the message.
Some common scam tactics include:
- Fake celebrity investment advertisements
- AI-generated voices posing as company executives
- Fraudulent video messages requesting urgent payments
- Fake financial experts promoting suspicious schemes
These scams can be very convincing because the faces and voices appear authentic.
The dangers of deepfakes
One of the biggest dangers of AI-generated media is the spread of misinformation. When fake videos look realistic, it becomes harder for people to distinguish between genuine footage and manipulated content.
This confusion can weaken trust in digital information. If people start questioning every video they see, even legitimate news footage may become harder to believe.
Another concern is reputation damage. A fabricated video can harm someone’s personal or professional life, even if it is later proven false.
How to spot a deepfake
Detecting synthetic videos is becoming more challenging as the technology improves. It is not as easy as using AI detection software for a written text. However, there are still some signs that may suggest a video has been manipulated.
Carefully observing details can help identify suspicious media. Small inconsistencies often reveal that artificial intelligence played a role in creating the footage.
Possible warning signs include:
- Unnatural blinking or facial movements
- Lighting that does not match the environment
- Voices that sound slightly robotic
- Lips that do not perfectly match the speech
Checking the source of the video is also important. If the content comes from an unfamiliar account or website, it is worth verifying before sharing it.
Can deepfakes be stopped?
Completely eliminating deepfakes may not be realistic, but several approaches are being explored to reduce their harmful use. Researchers and technology companies are developing AI tools that can detect manipulated media.
These detection systems analyse patterns in videos and images that may indicate artificial generation. While they are not perfect, they are improving quickly as the technology evolves.
Governments are also discussing new regulations aimed at preventing scams and election interference involving synthetic media. For example, the European Union’s groundbreaking anti-deepfake legislation, which is a law designed to regulate artificial intelligence across Europe, including technologies that create deepfakes
The future of deepfakes
Artificial intelligence is advancing rapidly, and deepfake technology will likely become even more realistic in the coming years. In some industries, this technology could have positive uses.
Filmmakers are already experimenting with AI techniques to recreate historical figures or digitally modify actors in movies. Similar tools could also be used for educational simulations or creative storytelling.
As the technology improves, understanding what are deepfakes will become increasingly important. Knowing how these videos are created can help people navigate the digital world more carefully.
Why understanding deepfakes matters today
Deepfakes are no longer a niche experiment used only by AI researchers. They are becoming part of everyday internet culture and digital communication.
From celebrity videos to online scams, artificial intelligence is reshaping how media is created and shared. Knowing what are deepfakes can help people recognise manipulated content and avoid being misled.
As technology continues to evolve, media literacy will become an essential skill. Recognising suspicious videos may soon be just as important as recognising spam emails.
