The increase in the use of content generated by AI has compelled businesses to check and verify the originality of the content. It is imperative for digital marketers and SEOs to guarantee that Google correctly indexes a website's content. 

There are many plagiarism detection tools available in the market which specialize in the detection of AI-generated content, plagiarism, and duplication. In this write-up, we will discuss how you can check for AI plagiarism using different tools. Let’s get into it. 

How To Detect AI-Generated Content?

According to Muhammad Abdul-Mageed, a researcher in Natural Language Processing and Machine Learning at the College of British Columbia, one of the most effective ways to achieve this is by training the model on texts composed by humans and machine-generated text to enable it to differentiate between the two.

Various techniques can be employed to identify content generated by AI. One widely used approach involves utilizing software that examines various aspects of the text, such as the language used, formatting, structure, and the recurrence of particular keywords. Moreover, Large Language Models (LLMs) can also be utilized to detect AI-generated text.

CopyLeaks has developed an AI Content Detector that is capable of identifying content generated with artificial intelligence, including content created with ChatGPT, with a remarkable 99.12% accuracy rate. 

This plagiarism detector has several applications, such as protecting websites from Google penalties in SEO, ensuring academic integrity and authenticity of student work, verifying the originality of books and articles in publishing, and preventing harmful reviews on websites. It also provides integration with API and LMS platforms. 

This plagiarism and AI checker can be used online by uploading and scanning text, or through a free Google Chrome extension that checks social media posts and news articles on your favorite sites. 

The monthly or annual cost of using CopyLeaks depends on the number of pages to be detected, starting at $10.99 per month for up to 100 pages and ranging up to a customized plan for large websites.


Originally.AI is a plagiarism checker and AI detector that can identify if the scanned text was created using an AI tool. It was designed by a team of content marketing and GPT-3 experts for web publishers, content agencies, and website buyers. 

This online plagiarism checker enables them to search for plagiarism cases, monitor their team's activities, and soon check the originality of an entire website. Originally.AI can also detect content generated with ChatGPT and GPT-3.5 (DaVinci-003) with the same level of accuracy as GPT-3.

In addition to its plagiarism detection capabilities, Originally.AI also provides APIs that can integrate AI detection into the content creation workflow or a custom tool. The tool's pricing model is based on credits, with prices starting at $0.01 per credit. One credit can scan up to 100 words of text.


Grammarly is a popular online grammar checker that also can be used as a writing assistant. It uses a combination of AI technologies, including machine learning, deep learning, and natural language processing, to not only improve writing but also detect copied text.

Additionally, it also has a feature that checks your content for plagiarism. However, Grammarly's detailed plagiarism statistics are limited due to its paywall. Grammarly can detect plagiarism but unless users have the premium version, they can't do much. The Premium version costs $12 per month. 

Despite this limitation, Grammarly has reportedly detected plagiarism and other writing issues in a few pieces of tested text.

OpenAI Text Classifier

OpenAI, the company that owns ChatGPT, has also released an AI plagiarism checker called the AI Text Classifier. This finely tuned GPT model predicts if the entered text has been written by a human or AI.

The AI Text Classifier has been trained on pairs of data, including inputs from both humans and AI. This makes it easy for the tool to identify plagiarized AI text. The app works across all kinds of text and is available on the company's website. 

OpenAI has cautioned that the tool isn't completely reliable yet and shouldn't be used as the sole way to detect copied text. Despite this, a few tests were performed by copying content from Beebom and Wikipedia, and the tool was able to easily identify human-written text. 

This free AI plagiarism checker is one of the best free-to-use options. However, it requires a minimum text input of 1,000 characters.


GPTZero is a popular AI plagiarism checker that has received good reviews from many users. It uses statistical data and an algorithm to check the content for originality, perplexity, and burstiness while identifying if the text is human-written or AI-generated. 

It occasionally misidentifies human-written text as AI-generated but such instances are rare. GPTZero provides specific metrics, a feature that sets it apart from other plagiarism checkers and is available for free.


GPTRadar is another tool that you can use to check for AI plagiarism and if a given piece of text is written by a human or AI-generated. The tool, which is based on GPT-3, has a simple website interface but effectively performs its function. GPTRadar separates the text into sections based on whether they were created by humans or AI and offers other details such as token probability and distribution. 

Crossplag AI Content Detector

Crossplag has developed an AI plagiarism checker that is specifically designed to detect AI-generated text in student assignments. The tool can handle up to 1,000 words per check and has been trained on a fine-tuned model of RoBERTa, using the Open AI dataset, which makes it highly effective at identifying copied text. Although still in the testing phase, the tool is capable of swiftly detecting instances of plagiarism. 

To test the tool, a combination of human-written and AI-generated text was combined, with a predominant human element, to evaluate its effectiveness in detecting the majority of the plagiarized text. Despite taking slightly longer to process, the tool provided a satisfactory output, indicating a 4% likelihood of the text being AI-generated. 

Crossplag intends to make the tool available to educational institutions, but for that to happen, the language support will need to be expanded beyond English. 

Writefull GPT Detector

One of the newest and widely used AI tools for detecting fake tweets online is Writefull's GPT detector. This simple-to-use tool is trained on various datasets to identify AI-generated texts and is quick to detect, making it usable in real-time.

This AI plagiarism checker plans to incorporate GPT-4 support and update its current model in the near future. While there is no paid subscription for this tool, this artificial intelligence technology tool mentions an unspecified daily quota. Nevertheless, the GPT detector is among the best AI plagiarism checkers currently available. 


Plagibot is an AI plagiarism checker that offers users the ability to upload various document types, including Word files and PDFs. The company has designed the AI checker to be user-friendly, with a friendly user interface. Plagibot keeps its database up-to-date by scraping the web every hour.

Users can contact the company for pricing information if they wish to upgrade to a paid tier.


AI-generated content and plagiarism detection have gained significant attention in recent years. AI systems, such as language models, can generate human-like text based on the input they receive. In the age of AI-generated content, plagiarism checking has become more important than ever. However, the use of AI-generated content raises concerns about originality and plagiarism. Since AI models are trained on existing texts, there is a risk that the generated content may resemble or replicate existing works, potentially leading to unintentional plagiarism. 

With the sheer volume of information available on the internet, it can be challenging to ensure that your content is original and unique. To address this issue, plagiarism detection tools have evolved to keep pace with AI-generated content. These tools utilize advanced algorithms to compare a given piece of content with a vast database of existing texts to identify similarities or matches. They can detect instances of plagiarism, whether the content is generated by humans or AI.

Our list of 10 best plagiarism checkers for AI-generated content will help you identify AI-generated content and detect plagiarism in a given text. These tools are user-friendly and accurate and offer a range of features to help you identify any potential plagiarism. By using these tools, you can ensure that your content is original and meets the high standards of integrity and quality that readers expect. Overall, AI and plagiarism detectors contribute significantly to maintaining originality, authenticity, and academic integrity in various domains, supporting the ethical creation and dissemination of content.

Other Frequently Asked Questions About AI generated Content

Does Google penalize AI content?

Google's Helpful Content Update reinforces the search engine's aversion to AI-generated content and its desire to prevent the spread of low-quality text created primarily for search engines rather than human readers.

However, there is a way to produce high-quality AI-generated content without incurring penalties from Google or alienating users. The solution lies in data. 

As strategic Growth Advisor Kevin Indig has noted, "The most significant differentiator will be the inputs (data) that companies can utilize to create content." This is where structured data becomes critical.

Is AI content good for SEO?

There isn't a definitive right or wrong approach to using AI-generated content for SEO. To generate concrete and lasting business benefits, it's crucial to establish workflows in which humans and machines collaborate. This involves leveraging language models such as GPT-3 while simultaneously maintaining oversight of content quality and semantic precision. 

In this workflow, humans are primarily responsible for cultivating semantically-rich data in Knowledge Graphs. This is the sole way to expedite content creation, support the editorial team's efforts and scale SEO.

Is AI generated content plagiarism free?

From a technical standpoint, content generated by artificial intelligence cannot be considered plagiarism. Plagiarism refers to the act of copying someone else's work, either verbatim or through paraphrasing, to avoid detection. 

AI-generated content is created through complex algorithms and language models, and as such, it is an original piece of work. However, it is still essential to consider the ethical implications of AI-generated content.
