July 8, 2024 Undetectable AI Review

The development of AI tools brings us improved efficacy, tons of ideas, and new dilemmas. Considering how popular these writing tools have become companies, professors, and professionals now use AI-detection tools to counteract and detect purely AI-generated texts. 

Now, many tools claim to create or generate undetectable AI, and that’s why this review will delve into the performance of and compare it with Duey.Ai, another leading player in the field. By testing both tools against various AI detectors, we aim to evaluate their bypass efficiency and determine which one truly excels in creating undetectable content and achieving AI detection bypass.

What Is is an advanced AI tool designed to create text that closely mimics human writing. Its primary advertised feature? The ability to create undetectable AI-generated content. It’s a great tool for content creators, marketers, and business owners who need authentic-sounding text to bypass AI detection systems. Key Features and Capabilities

  • Advanced NLP algorithms: uses cutting-edge NLP techniques to produce high-quality, human-like text. These algorithms ensure that the generated content flows naturally and maintains coherence, making it difficult for AI detectors to identify it as machine-generated.
  • Customizable output: Users can customize the output to match specific tones, styles, and formats. This feature is particularly useful for tailoring content to different audiences or platforms, enhancing the tool's versatility.
  • Detection evasion: One of the standout features of is its ability to evade detection by popular AI detectors. The tool continuously updates its algorithms to stay ahead of detection technologies, ensuring that users can produce content that remains undetected.
  • Integration capabilities: can be integrated with various content management systems (CMS) and other digital tools, streamlining the workflow for content creators. This integration capability should boost productivity and seamless content updates.

Does Really Work? The Comparison and Results

To make the testing phase more interesting and get the real results you are looking for we’ll compare a simple AI-generated text humanized on and Duey.AI. This way we’ll be able to see how the tools perform on major AI detection platforms such as Copyleaks, Originality, and GPTZero. 

We’ll also compare the results and find out if the tools can bypass the AI detectors.

  • Step 1: We’ll write a simple prompt for ChatGPT and let it generate something interesting;
  • Step 2: Then we’ll take the generated text and run it through and Duey.AI;
  • Step 3: Next, we'll scan the humanized texts through AI detectors and show the results.

Here is the simple prompt we’ll use:

“Write an informative and engaging article on the importance of maintaining a healthy diet for overall well-being. Discuss the various benefits of eating nutritious foods, such as boosting energy levels, enhancing mental clarity, and supporting immune function. Include tips on choosing the right foods, considering factors like nutritional content, balance of macronutrients, and variety. Additionally, touch on the health risks associated with poor dietary habits, such as obesity, heart disease, and diabetes, and how a healthy diet can help mitigate these risks. Conclude with practical advice for incorporating healthy eating into daily routines and suggestions for planning and preparing meals to ensure consistency and enjoyment. 300 words max”

The AI detectors we’ll be using this time are:

While there are many different AI detectors on the market, these three are usually the most reliable sources. 

Copyleaks is famous for its robust plagiarism detection and AI content identification, making it ideal for academic and digital content creation environments, but many people in the industry claim it’s not the best tool out there. So, we combined the results from Originality as they are a favorite among content creators for their detailed detection of AI-generated texts. Lastly, GPTZero specializes in detecting GPT-based models, providing a focused approach to identifying text generated by tools like ChatGPT. 

By using three different detectors we ensure the results are thorough and varied, which will give us a clear picture of how well and Duey.AI bypass AI detection and maintain content integrity.

As you can see, the Copyscape AI detection tool considers both humanized texts from and Duey.AI to be completely human. Although both tools generated text that bypassed the Copyscape detection, the version Duey.AI tool created flows more naturally and sounds genuine. 

Originality Results for

Duey.Ai Outperformed by Achieving a Lower AI Detection Score on

The chart above illustrates the originality results for and Duey.AI. achieved 83% originality, with 17% of the content identified as AI-generated. In contrast, Duey.AI performed better, with 95% of its content deemed original and only 5% recognized as AI-generated. 

Keep in mind that Originality uses the most demanding algorithms to test the AI-generated text, and almost all tools fail this test. This comparison underscores Duey.AI's superior ability to produce text that passes AI detection and maintains a higher level of originality, making it a stronger contender for generating authentic and human-like text.

Even though it’s not 100% human this score is still considered good among experts, publishers, and marketers.

GPTZero Results for

GPTZero Recognizes 1% Content As Human Written by StealthWriter.Ai

GPTZero Results for Duey.AI

GPTZero Recognizes 98% Content as Human Written by Duey.Ai

GPTZero Bypass Score of and Duey.AI bypassed GPTZero with a lower AI detection score compared to

According to GPTZero results, Duey.AI's content is 98% classified as human, with only 2% identified as AI-generated. In contrast,'s content is 88% classified as human and 11% as AI.

This major difference in percentages that are deemed as AI-generated texts shows us once more that Duey.AI scores better even on the most demanding platforms. 

Does Bypass AI Detection?

To determine whether can effectively bypass AI detection, we put it through rigorous testing using three of the most reputable AI detection tools: Copyleaks, Originality, and GPTZero. 

The results were enlightening and varied across the different platforms.


Known for its strong plagiarism detection and ability to identify AI-generated content, Copyleaks is a staple in academic and professional environments. When we tested text with Copyleaks, it performed admirably, with the tool failing to detect any AI-generated content. 

This indicates that's algorithms are sophisticated enough to create text that mimics human writing patterns convincingly.


Originality is a preferred tool among content creators and businesses due to its nuanced approach to detecting AI content. Our tests with Originality showed that had a detection rate of around 17%. While this is relatively low, it does indicate that some AI traits were still detectable. 

Originality's updates and advanced detection models make it one of the tougher tests for AI content, and's performance here highlights both its strengths and areas for improvement.

It’s good to have a comparison with stellar tools like Duey.AI and see that even the most sophisticated humanized text shows some AI-positive results on demanding platforms such as Originality.


Specializing in detecting text generated by GPT-based models, GPTZero provided the most challenging test.'s text was detected with an 11% likelihood of being AI-generated. 

This result, while higher than with Copyleaks, still demonstrates's capability to produce largely undetectable content, though not entirely foolproof against specialized detectors like GPTZero. This performance indicates effective AI-generated content evasion.

StealthWriter.Ai Performed Well Against CopyLeaks and GPTZero but was Least Efficient Against

Final Verdict shows a strong ability to bypass AI detection tools, particularly with platforms like Copyleaks. However, more sophisticated detectors like Originality and GPTZero can still identify subtle AI-generated patterns in some cases. 

This performance indicates that while is effective, users should remain aware of the detection capabilities of various tools, especially when aiming for content that needs to be completely undetectable. Luckily there are other AI humanizing tools available, so make sure to test out the competition and find the right tool for your writing needs.
