Does CogniBypass Tool work?

A review of CogniBypass Tool.

CogniBypass tool is another Undetectable AI that specializes in rephrasing AI generated content. If offers a standard bypass tool where users can bring over their content from sources like ChatGPT or other generative AI sites and rephrase it to be undetectable, or so they claim. They also have CogniGPT which is a chat within CogniBypass.

Today we will be reviewing CogniBypass, specifically their bypasser to see if they beat the three big AI detectors: GPTZero, Originality, and most importantly, Turnitin. In order to be a true Undetectable AI, you should be able to handle all three handedly. We will also run the same test against StealthGPT to see which service is truly superior and which service works the best when seeking Undetectable AI.

CogniBypass specifically advertises their ability to pass Turnitin so this by far is the main concern of our test. Due to a recent upgrade by Turnitin, their AI Detector is catching all Undetectable AI's except StealthGPT. Let's see if CogniBypass is one of them.

Test Preparation

First things first, we have to come up with some content to have CogniBypass tool and StealthGPT to rephrase. Let's use trusty ChatGPT to whip up a 'null' text that will serve as the text we will put through each bypasser/humanizer.

We had ChatGPT write a bit of background on one of the most famous men alive, Elon Musk. Now let's take our ChatGPT content and bring it over to CogniBypass Tool.

Our CogniBypass Tool Generation

This is the text we received from Cognibypass. On the CogniBypass Tool they allow you to choose your target for text to beat certain AI detectors. We choose Turnitin,. On the bottom of the screen you can see they feature a greencheck mark to us implying this text should Bypass Turnitin and Is this true? Let's find out! But first let's get StealthGPT's text.

StealthGPT's output

Okay now that we have our text from both services we can start comparing the results.

Testing against GPTZero, Originality, and Turnitin


Let's start with one of the biggest AI detectors that kicked off this arms race, GPTZero. They are one of the biggest AI Detectors in the world. In the beginning they were very easy to bypass, but since their beginnings they have conducted several updates and now it is very hard to beat GPTZero. Let's see how the CogniBypass Tool holds up against this difficult detector:

CogniBypass Tool GPTZero Result

Hmm...definitely not great. GPTZero is showing above a 50% chance of this text being AI generated. But its not all bad since there's a chance its not. However below the score it denotes that 18/18 sentences were AI generated. That would probably arouse suspicions.

Let's take the result from StealthGPT and see if it suffers the same fate as CogniBypass Tool. Afterall, GPTZero has significantly upgraded their systems, its possible they will pick up on it.

StealthGPT GPTZero Result

Wow, StealthGPT scores an impressive 1% probability that the text was written by AI. That is pretty darn good if you ask us. If you submit this text in any setting its very unlikely to be picked up. Also GPTZero denotates that 0 of the 21 of the sentences in the text are likely to be AI generated. This is a fantastic result, but it is only one AI detector. Perhaps Cognibypass Tool will do better on others.

Originality is a lesser known AI detector but it is still one of the big three in our opinion. It has been historically one of the more accurate detectors we've seen. Their latest 2.0 model has proved very difficult to bypass. Again, we have another tough test for both StealthGPT and CogniBypass Tool. Which one will prove themselves worthy of calling themselves truly Undetectable? Let's run the CogniBypass Tool text first and see what happens:

CogniBypass Tool Results

Well unfortunately CogniBypass Tool scored even worse on's detector. It is not looking that good. But again let's reserve judgement until the end. Also let's not forget to check StealthGPT's results to see how it does.

StealthGPT Results

Once again, StealthGPT scores high marks against's detector. It is proving itself to be resilient against multiple AI detectors, scoring very little on the AI side to none at all.

And now the test you have all been waiting for...Turnitin


Turnitin is the world's largest AI detector, that is because it is used by the Turnitin platform. Turnitin is one of the most used academic softwares in the world, servicing millions of students and thousands of institutions of higher learning. When any assignment is submitted through Turnitin, it automatically checks the assignment against it's AI detector. Due to the usage of the platform natively, this makes their AI Detector the #1 in the world naturally. Up until recently, it was very easy to bypass Turnitin AI Detection, but an update a few days ago has led to several services failing to bypass them, with the exception of StealthGPT. CogniBypass Tool markets explicitly on their ability to beat Turnitin, so let's see if they rise to the occasion.

CogniBypass Tool Turnitin Result

This is the best score that CogniBypass Tool received. Unfortunately though it has a significant amount of the text, 33%, caught as AI. This could lead to trouble, especially when you run the same text against multiple AI detectors. It does not hold up to scrutiny. If you were a student and handed this in, you could be in pretty big trouble.

Now let's see if StealthGPT still continues to bypass Turnitin's AI Detector after their latest update:

StealthGPT Turnitin Result

As expected, StealthGPT absolutely crushes Turnitin, remaining top dog in the Undetectable AI space.

Final Thoughts

CogniBypass Tool and StealthGPT are two tools that promise users the ability to generate Undetectable AI responses. So far, only one has delivered safe results, and one delivered lackluster results. Despite receiving a greencheck mark on the CogniBypass Tool's website it failed to bypass GPTZero,, and Turnitin, making it very dangerous to use. On the other hand StealthGPT continues to dominate the Undetectable AI space, easily bypassing GPTZero, and Turnitin.

StealthGPT is able to beat most AI detectors due to the way it was built from the ground up. We cannot speak to how CogniBypass Tool was built but we are aware most AI tools are built with very simple prompts from OpenAI's GPT models. Unlike most AI tools out there, StealthGPT was built and trained on hundreds of hours of human styled writings that make it uniquely different from any other AI writing tool on the market. That is how StealthGPT is and continues to remain the best Undetectable AI on the market.
