Undetectable AI is an online tool that checks if your writing was written by AI and also offers a tool to “humanize” AI writing so your writing can bypass AI content detectors.

Undetectable AI does not work in its efforts to bypass our AI-detecting tool, Winston AI. It also makes the AI writing from a tool like ChatGPT significantly worse quality. Pointless is the word that comes to mind.  

Why is it called Undetectable AI? 

This tool is called Undetectable AI because the aim of the tool is to modify AI-written content so that it does not get detected in AI-detecting tools.

Ok, Let’s back up a little.    

Many students and writers are using tools like ChatGPT to do their writing for them and pass it off as their own work.

Teachers and publishers need to know if this work is original so they use an AI detector like Winston AI to check it(Our tool Winston AI has a 99.98% accuracy rate for AI-generated content).

So now students can use a tool like Undecteable AI to modify the writing so it appears human written.

But does this work?

Let’s find out 

Testing Undetectable AI 

First, let’s create some writing with ChatGPT 

Now let’s show you how Winston AI works

Let’s copy the text above into Winston and see the results:

As you can see, we correctly predicted that the content was AI.

Now let’s put our text into Undectable AI.

You have two options Check for AI or Humanize

Let’s Check for AI first:

Undetectable correctly identifies the work as written by AI and gives an AI Detection likelihood by several tools(Winston is not there but we will get back to that).

Let’s try and “Humanize” the content

To do this you must promise to agree to “no academic misconduct”.

This time Winston predicted the text as 28% human.

It is also important to look at the quality of the text that Undectable AI has rewritten.

As you can see, the tool has resulted in some very poorly written English.

Orphaned at an age he primarily educated himself. Also had some formal schooling. 

Not likely to win a Nobel Prize for Literature, I’ll say that much. 

Undetectable AI Features

Undetectable AI tools are built into one user interface that allows you to “check” if your writing will appear as AI content in some online AI-detecting tools. 

AI content detector 

As discussed above, an AI detector checks if written text is written by AI or a human.

We saw that the Undetectable AI detector worked for the first ChatGPT essay but what if I ask ChatGPT to write in a quirky tone?

Undetectable AI’s detector found this text(ChatGPT’s quirky essay on Alexander Hamilton) to be human-written  

You can see on the right-hand side that Winston AI correctly identified the text as AI written. 

Undetectable AI also provide their AI detection likelihood which often seems to agree with their analysis.

I am not sure where they are getting their information about these other tools but they tend to agree with their analysis. 

I was curious so I also tested this article with GPTZero and they also concluded that the text was written by AI  which is not what the AI Detection Likelihood says. 

Humanizer Tool

A humanizer tool claims to make AI text sound more human but in reality, it just uses an algorithm to change the text similar to a paraphrasing tool like Quillbot. 

The text doesn’t sound more human but rather it is an attempt to bypass AI detectors. As you saw from the example above, the grammar doesn’t sound natural and the syntax is unnatural. 

To be honest, ChatGPT can already write text that can be difficult for most people to tell whether it was written by a human or AI so the need for a “humanizer” tool seems to be more of a marketing term. 

Human Typer Tool

The Human Type tool is designed to mimic each word being typed like a human would. Most people when they use an AI tool copy and paste the text into a document. 

One way of checking if the person wrote the article is to check the history of the document and see if it was pasted in or written section by section. 

Undetectable AI Pricing

The Pricing of Undetectable AI depends on how many words you need to detect/humanize.

Here are some examples of prices per month:

These prices do not include VAT.

You can also save money by purchasing yearly plans.

Undetectable AI Alternatives

Here are some alternatives to Undetectable:


StealthWriter is a similar tool to Undetectable as its main feature is a rewording tool that modifies text so that it can bypass AI detection. 

StealthWriter is also more expensive than Undetectable AI but that doesn’t mean that it works any better. You can read our review for SteathWriter here

Stealth GPT 

Stealth GPT is another tool that attempts to edit text in an attempt to trick AI detectors. They give the text a stealth score after editing the text.
