Stealthwriter.ai Deep Review: Can It Bypass All Detectors?

Want to make AI-generated text like human-written? Humanized tools are made for that.  

Stealthwriter.ai is a popular one. 

However, not all tools work well to bypass the AI radars successfully. 

Today, we will test Stealthwriter.ai to see if it works as promised. Read this article to learn how accurate its technology is and whether you should pay for it. Let’s start!

What is Stealthwriter.ai?

Stealthwriter.ai has three features: an AI humanizer for humanizing AI text, an AI detector, and the ability to generate undetectable AI text directly.

Its product page displays the effect of bypassing all AI radars, including Originality AI, Winston AI, GPTZero, ZeroGPT, and Turnitin. Moreover, it promises to produce outputs without errors and awkward phrasings while retaining a human touch.

Why Do We Do This Test?

The introduction sounds attractive. So, what makes us test it today? 

Many people use AI to speed up work efficiency. Content writing, including blog posts, scripts, marketing materials, etc., is a big part of this. 

It's not a bad thing to use AI for writing assistance. However, poor AI work can have adverse effects. Similarly, Some AI humanizers also produce low-quality content; they use different words with AI or intentionally add grammar errors.  

So, our review blog series aims to find out: 

Are tools like Stealthwriter.ai truly the shield against AI detection they claim to be? 

Can it deliver error-free content without relying on nonsensical word swaps typical of other humanization tools? 

We will walk you through it to see if it lives up to its promises, helping you save on tools that don't meet your writing purpose. 

Testing Stealthwriter.ai  

Methodology Explanation  

1. We made the test copy with ChatGPT-4.  

2. Stealthwriter.ai will then make it a human-like version. 

3. After humanization, we will use five prominent AI detectors to check the AI score. 

4. The writing quality is also a part of the test. It includes both readability and grammar. 

5. The last step is to analyze the change in the AI detectability percentage after correcting all grammatical errors.

Testing Text

Topic: How to Survive a Jet Lag in First Persona 

Words: 280 words.

We asked ChatGPT-4 to write the topic in the first person at a general reading level. This length and writing style are widely applicable in many scenarios. 

With this content, we can also examine whether Stealthwriter.ai can maintain the human touch in writing by checking its engaging and interactive writing.

Humanized by Stealthwriter.ai:  

Now, let's put the pure AI text into Stealthwriter.ai. We use the Ninja mode, dragging the level to “More Human'' at its maximum.

Results: Stealthwriter.ai's Efficiency in Bypassing AI Detection

Then, we get the undetectable content. You will notice that it provides five variations, each with a self-detect AI score. We selected the output that Stealthwriter indicated as having the highest confidence in human-like quality, scoring an impressive 4% AI detectability. 

(But please note that the humanized version is 100 words longer than the original one. We will discuss this later.) 

Next, we used five well-known AI detectors to check if it's as it says.

AI Score After Stealthwriter.ai Humanized

What Do the Results Say About Stealthwriter.ai’s Ability to Bypass AI Detection?  

Obviously, it didn't bypass all the five detectors as claimed. The best mark is 0%, scored by the Quillbot and the Writer. GPTZero and ZeroGPT came in close second. Originality.ai, however, detects a 40% AI possibility. 

The initial score is not very bad among all the reviewed tools, as Originality.ai is robust in AI detection. But this does not mean it’s good to go yet. In the next part, we will examine its writing to see if it balances the AI score and content quality.

How Good is the Quality of Stealthwriter.ai’s Humanized Text?

Here, we choose Grammarly for the scoring. Its Pro version gave an overall score and suggestions on grammar correctness, writing clarity, and more. 

Let's see what it says about Stealthwriter.ai's humanized text.

1. Overall Score, Grammar & Quality

GrammarlyPro score: 84 out of 100.  

It seems a decent score, representing that the text is well written and likely understandable for readers.

But wait, 17 review suggestions for Correctness and 10 for Clarity?  

Well, this is a bad signal. It indicated that the text needs to perform better at grammar rules and information delivery. 

Moreover, as mentioned before, the humanized text was nearly 100 words longer than the original. So you will see there are wordy expressions, which invoke many suggestions for rephrasing sentences. It also suggests that Stealthwriter.ai might be introducing unnecessary verbosity into the text.

2. Accept Grammarly's Suggestion

The analysis of the content naturally leads us to the next part. Will these errors trick the AI detectors into thinking it's the text as human-written? What will happen if we amend the text according to the suggestions? 

We addressed all of them, increasing the text’s overall score to 99 out of 100. We then use the five detectors to recheck the AI likelihood. 

3. AI Detection Scores After Grammarly Improvements: 

Findings:

Surprise. The score differs from the initial table. Quillbot and Writer showed almost no change. However, the other four tools saw a sharp increase, particularly Originality.ai, and GPTZero, which almost wholly identified the text as 100% AI-generated post-improvement. 

What's the conclusion? A better quality, a higher AI score? 

Not exactly. It implies that Stealthwriter.ai may mimic human writing errors in grammar to trick the AI detectors. When we remove these errors, the detectors calculate the AI footprint. So it's not a universal trick., especially when you need to bypass a strict AI radar.

How User-Friendly is Undetectable AI?

From our hands-on testing, we found using Stealthwriter.ai is straightforward. There is no technical knowledge required, everyone can use it. And its response time is short. 

However, we would like to remind you of two limitations. One is the input restriction. The free trial only allows 300 words per request, which is not enough to test a whole article.

The other flaw is no writing purposes options. There are no features for you to process content for specific contexts, like blog posts or essays.

Stealthwriter.ai Pricing

Stealthwriter.ai offers a tiered pricing structure that caters to different usage needs:

Free Trial

300 words per request. 

Package Pricing

All in all, Stepthwriter.ai excels in making undetectable content under Quillbot and Writer. But it fails to evade the others. The reason may be the differing detection principles and intensity. 

Anyway, a good humanizer should get both a low AI score and a high writing quality. What's the following tool we will review? Stay tuned!
