Artificial Intelligence (AI) has become a double-edged sword in content creation and management. On one side, AI writing software and content generators are considered to be invaluable for producing and optimizing content quickly. Conversely, AI content detectors help ensure that AI-generated content isn’t plagiarized and reads more like a human rather than a machine. This article delves into this dichotomy of AI-generated content and AI content detection, emphasizing the best AI content detectors for you to try.

What are AI Content and Plagiarism Detectors Used For?

Low-quality AI content or plagiarized work can be a ticking time bomb for a business. If you don’t catch subpar content, it can trigger a host of problems:

  • Immediate damage to reputation if work is found to be plagiarized
  • Potential penalties from Google for low-quality content, as per changing E-E-A-T standards
  • Overpayment to writers who may not have done the work they claimed to have done
  • Possible future copyright issues
  • Content that is merely average rather than exceptional

AI content detectors come to the rescue by helping to:

  • Estimate if AI writing tools generate content
  • Find copied or plagiarized content
  • Assess the percentage of original content of a piece

We all know that using AI carte blanche has inherent risks and a few new possibilities. A more thoughtful approach is to use AI alongside human writing practices. AI writing detectors can serve an essential piece in understanding the content before you—whether you wrote it yourself or are grading or editing the work of others.

Content detection is only going to get more important for businesses, schools, and individuals. Choosing the right tool can help you have the confidence to know, as best as possible, whether the content you are looking into was created with AI or by a human.

What is an AI content detector?
An AI content detector is a tool that uses artificial intelligence (AI) to identify content produced by an AI writing tool. This tool is valuable for businesses aiming to guarantee the authenticity of their content and for students seeking to prevent any unintended plagiarism. Moreover, they are valuable for educators ensuring students' original work and moderators combating fake reviews and spam content, thereby upholding authenticity and integrity in various contexts.
Are AI content detectors reliable?
The reliability of AI content detectors varies depending on the tool and the content being analyzed. Some tools are more accurate than others, and some types of content are more difficult to detect. We recommend using Winston AI if you want the best chance of catching AI-written content.
Should I use an AI content detector?
Here are some situations where you might want to use an AI content detector:
  • Business owner who wants to ensure your content is original
  • Student who wants to avoid plagiarism
  • Content creator who wants to make sure that others are not copying your content
  • Teacher who wants to ensure their students are not plagiarizing
  • Researcher who wants to make sure that your research is original
AI content detectors can be a helpful tool in these situations. However, it is important to note that AI content detectors are not perfect. They can sometimes incorrectly identify content as being AI-generated, or they may miss content that AI has generated. Therefore, using AI content detectors in conjunction with other methods of detecting plagiarism, such as manual checking is important.
How accurate are AI content detectors?
AI content detectors vary in accuracy. Some reports have pegged Winton AI accuracy at 99% and Originality.ai at 95.93%. Most are getting quite good. The challenge is that LLMs are rapidly getting better at the same time. There is a need for constant training, testing, and innovation for AI detection tools.
Do AI content detectors work across different languages?
CopyLeaks, an AI content detector, supports the verification of content in multiple languages such as English, Spanish, French, German, Portuguese, Italian, Russian, Polish, Romanian, Dutch, Swedish, Czech, Norwegian, Japanese, Korean, and Chinese (Simplified & Traditional). However, it's important to note that CopyLeaks currently only supports textual content and does not include support for coding languages.
How can I beat AI content detectors?
You can utilize advanced AI rewriter tools like Jasper to try and beat AI content detectors. Jasper is a powerful AI-powered writing tool that enhances your content using state-of-the-art AI and NLP techniques. It can analyze and rewrite your content to make it more engaging, effective, and error-free. Additionally, Jasper can generate new content based on user prompts, making it one of the top AI writing tools available. However, the best chance at beating these tools in the long term is to create original, human-generated content. Simulated human content is still different from human content and may be caught by these tools.
How can I detect AI content with Copyleaks?
Copyleaks provides a user-friendly AI-content detector through their website, allowing users to screen text for AI-generated content using AI-based contextual analysis. Additionally, they offer a Chrome Extension that detects AI content on browsed web pages.

Can AI content detectors detect a PDF?
Yes, SciSpace's AI detector can detect content in PDF format. Users can simply paste the content or upload the PDF file to the text editor, enabling quick and easy detection reports for AI-generated content.
How do AI content detectors work?
AI content detectors typically employ language models to assess the input text by asking whether it resembles the kind of text it would generate. If the answer is affirmative, the detector claims that the content is AI-generated. These models focus on two aspects: perplexity and burstiness. Perplexity determines the text's unpredictability or confusion to an average reader. On the other hand, burstiness analyzes the sentence structure and length variation.
Is there an AI detector for ChatGPT?
Most AI content detectors and checkers are specifically designed to catch outputs from ChatGPT. This means tools like Winston AI and GPTZero are suitable AI detectors to identify content generated by ChatGPT. With a few simple clicks, they easily provide a summary of text likely to be AI-generated.

  1. Thanks so much for the list! Now the challenging part…how quickly will the list change considering how quickly ChatGPT/A.I. is evolving.

    • ChatGPT is only the tip of the AIceberg. Lots of different LLMs are being developed and many for particular use cases (such as content analyzing and AI detection). I think some of these bigger AI detectors will do well for sometime. What I see as a bigger immediate problem is how Google analyzes content (and how it’s going to change over the next 18 months).
