AI tools trained with the grammar structure and patterns of different languages are perfect tools for text-based content generation. However, the increasing use of AI-generated content has led to low-quality, uninteresting, repetitive, and unethical content. If you want to find out whether a content is AI-generated, there are AI tools you can use.

In this article, we will explain what AI-generated content is and how you can quickly detect it.


  • The popularization of AI tools has led to the spread of fully AI-generated content.
  • AI-generated content is identified as plagiarized because it is not produced by the author.
  • If you want to detect AI-generated content, you can use AI plagiarism checkers or AI content detectors.
  • The best AI tools you can use for AI-generated content detection/plagiarised content are TextCortex, Copyleaks and Grammarly.

What is AI-generated Content?

Any output in text, audio, visual and video formats produced by artificial intelligence is called AI-generated content. While AI-generated content is mostly harmless and useful, it also has unethical uses. AI-generated content that encourages readers to spend money or requires expertise may lead to errors and misdirection.

Can AI detection tools identify AI-generated content?

AI detection tools can detect AI-generated outputs using large language models and technologies such as natural language processing (NLP) and machine learning. The more trained data an AI content detector has, the more accurate output it will give.

Is using AI-generated text considered plagiarism?

Any sentence not written by the author but written by another individual or AI is identified as plagiarism. Since AI-generated content is not written by the author, it is considered plagiarism and should not be used in academic writing. You should avoid using AI-generated content in your essays and research papers unless your professor gives permission.

When should you avoid AI-generated content?

You don't always have to avoid using AI-generated content. If your content is helpful and honest, search engines will not exclude your AI-generated content from search engine results.

However, you should avoid using AI-generated text in academic writing, content that encourages people to spend money, and topics that require expertise. For example, you should not use AI-generated content in articles such as pet care, health, finance, diets, and product reviews. Since these topics must be written with experience and expertise, AI-generated ones will be low quality and misinformative.

How to Detect AI-Generated Content and Plagiarism

There are two basic methods you can use to detect AI-generated content. Let's take a closer look at them.

AI Content Detectors

The easiest method to identify AI-generated content is by using AI content detectors. These detectors use trained data and large language models to analyse whether the given content is written by humans or AI. Moreover, AI content detectors are easy to use; simply enter the content and click the "Scan" button.

Although most AI content detectors are based on the GPT-4 language model, there are AI content detection tools that can also identify content generated by language models such as Bard and Llama.

AI Plagiarism Checkers

There are two reasons why your content is considered plagiarized: the content contains sentences from another source, or it is AI-generated.

For this reason, you can evaluate whether any content is AI-generated by using AI plagiarism checkers. If the content scan results in 100% plagiarized, it is most likely AI-generated.
