10 Best AI Plagiarism Checkers to Detect AI Content
Generative AI has taken over the world of content as well as creative writing by storm. Today, artificial intelligence can produce a 4000-word article in just the blink of an eye. However, this technology is increasingly becoming a concern among the writers’ and publishers’ communities.
Rapidly generated content from AI tools is often misleading and repetitive. Moreover, it divorces authenticity and uniqueness from any written form of content. So, to produce original and reliable content, the usage of AI-powered plagiarism detectors has become essential for any institution or organization. In this article, we will be discussing some of the best tools to detect content generated with ChatGPT.
How Does An AI Detection Software Work?
Content generated by AI writing tools is not necessarily a mere duplication of someone else's work but is a highly sophisticated writing form that requires AI-powered algorithms for detection. Thus, AI generated content for SEO is checked with the help of language models-based AI detectors. These AI detectors check the content for its perplexity and burstiness. The lower the score of these two, the higher are the chances for a content to be AI generated.
Here is how these two parameters can be explained in simple words….
- Perplexity is the measure of the predictability of any text. Human writing is usually highly unpredictable and thus has a high perplexity score. AI generated content on the other hand is less likely to be random, hence it is easier for any machine language to predict the next word in the sentences. Thus, content generated by AI will always have low perplexity score.
- Burstiness, on the other hand, is the measure of variation in the sentences. Usually, the content generated from ChatGPT is very repetitive and follows a pattern that may fool any human eye. However, for an AI content detector, it's simply a matter of marking content with low burstiness, i.e., less randomness in the successive sentences in a written piece of content.

Limitations of Online AI Detectors
While AI plagiarism checkers offer remarkable capabilities, it is important to acknowledge their limitations. Some of the limitations you may encounter when using these tools are:
- False positives: AI algorithms can sometimes identify similarities that are not indicative of plagiarism. This may occur when the same common phrases or idioms are used in different contexts.
- Limited access to sources: AI plagiarism checkers rely on the sources they have access to. If a source is not included in their database, they may miss potential instances of plagiarism.
- Inability to detect paraphrasing: AI algorithms may struggle to identify plagiarism when the text is heavily paraphrased or rephrased. These instances may go undetected.
- Non-textual content: AI plagiarism checkers primarily analyze text-based content. They may not be suitable for detecting plagiarism in non-textual formats such as images or videos.
- Language limitations: AI plagiarism checkers may not be equally effective for all languages. Some tools are specifically optimized for certain languages, potentially resulting in reduced accuracy for others.
It is important to consider these limitations and exercise caution when interpreting the results provided by AI plagiarism checkers.
