AI-generated content (AIGC)
Text, image, audio, video, or program code whose substantial part was not created by a human but by artificial intelligence, typically based on human instructions.
In plain terms
AI-generated content is anything created by an artificial intelligence system: an email draft, a product photo, a voiceover, a short video, or even a working program. You formulate what you want, and the machine produces it in seconds.
It is like a very fast, very well-read day laborer. It has seen countless patterns, so it can work in almost any style. However, it has not been on-site, has not seen the event, and does not know if what it writes is true. It provides what sounds probable and convincing.
This is different from traditional editing programs. A classic photo editor modifies an existing image. AI can also create a completely new image from learned patterns, even one that never happened in reality. Today, many editing programs have incorporated this capability. This is why it became both a useful work tool and a new source of deception.
How it works
- A model is trained on huge amounts of text, images, audio, or video, and in the process learns the patterns within them: how words follow each other, what a face looks like, how a sound rings.
- You give an instruction (prompt), for example: "write a polite reply letter" or "draw a sunset at Lake Balaton".
- The model generates the result step by step based on learned patterns. It assembles text token by token and typically cleans images from noise gradually.
- The result is usually a new creation, not a copy of a previous work. Rarely, however, it can reproduce a detail of the training material almost word for word. It can also carry the style, errors, and biases of the training material.
- In the best case, a human checks and corrects at the end, and the provider can mark the content with an invisible watermark or provenance data. If an AI agent works independently, the content can be published without human review.
An everyday example
You scroll through a social media site and stop at a touching photo of an elderly woman with her 100th birthday cake, with thousands of congratulations below. The woman does not exist: the image was created by an image generator to gather as many likes as possible for the page. Product descriptions for web stores or the voice of telephone customer service can be created in a similar way.
Who is affected
A common misconception
Limits and risks
- It can confidently state falsehoods: fabricated quotes, non-existent sources, or incorrect data, so always verify the facts.
- It is also used for fraud and deception, such as creating fake videos, voice cloning, or fake news, so always verify the source of suspiciously shocking or urgent content.
- The copyright status is uncertain: in many countries, works created purely by machines do not receive protection, and it is also debated which works were legally permissible to train the models on.
- Mass-produced, low-quality machine-generated content is flooding the internet, making it harder to find valuable, reliable information.
Similar, but not the same
- Deepfake – A deepfake is a type of AI-generated content that imitates a real person, object, location, or event in a deceptively lifelike manner, such as a famous person's face or voice. Most AI-generated content is not like this.
- Generative AI – Generative AI is the technology itself, while AI-generated content is what this technology produces.
- AI-assisted content – There, the human writes or creates the work, and the machine only edits, translates, or offers ideas; in AI-generated content, the machine performs the substantial part of the work.

A brief history
Machine-generated content is a long-standing research field, but the era of lifelike images was opened by generative adversarial networks (GANs), introduced in 2014. The general public met it en masse in 2022, when image generators driven by text prompts appeared, followed in November by ChatGPT.
Where things stand
By the end of 2026, machine-generated text, images, audio, and video will be a common part of daily work and the online space, often indistinguishable from human-made content. The transparency rules of the EU AI Act will apply from August 2026. These require providers to label machine-generated content in a machine-readable way. Those publishing deepfakes or machine-generated text on matters of public interest must disclose the artificial origin. The practices of watermarking and provenance are still evolving.
